Texas Instruments online test: quick answers
These answers are compiled from public candidate reports and prep guides, not from an official TI notice, and drives differ. The instruction screen of your own test is the final word.
| Question | Answer |
|---|---|
| How many questions and how long? | It depends on how many tracks you pick. A common pattern is a shared aptitude section of about 20-30 questions plus about 20 questions for each technical track, each block timed separately. One digital-design report describes 30 cognitive questions, 20 analog and 20 digital, each in 45 minutes (2 hours 15 minutes in all); a Software-track report describes 30 MCQs in 75 minutes. |
| Which tracks can I choose? | Up to two. Candidates choose from Analog, Digital and Embedded Software, and a 2024 IIT Kanpur intern account also lists Signal Processing. Your track scores decide which interviews you are called for. |
| Does it have negative marking? | Yes, on most reports. A digital-design candidate gives the marking as +1 for a correct answer and -0.25 for a wrong one, and FACE Prep notes negative marking in the aptitude section. Some write-ups do not mention it, so check the instruction screen. |
| Is there a sectional cutoff? | Yes, each section is reported to carry its own cutoff, and TI does not publish the numbers. FACE Prep puts a typical cutoff around 55-60% of a section. |
| What is the eligibility cutoff? | 7.0 CGPA is the figure most reports give, with about 60% in 10th and 12th and no active backlogs; some campuses differ. Analog and Digital are open to EE, ECE and related branches; Embedded and Software also take CSE. |
| Which platform is it on? | HirePro, according to the GfG reports for the digital, embedded and software tracks. |
| Is there coding in the test? | No. The online test is MCQ-only. Coding happens live in the embedded and software interviews, usually in C on a shared screen. |
| How many get shortlisted? | Very few. One on-campus report had about 24 of roughly 250 students shortlisted for the Software track and 2 selected; another drive called 53 students for analog interviews and 18 for digital. |
Texas Instruments interview questions by track
The interview follows the track you cleared in the test. These are questions candidates have reported on GeeksforGeeks, FACE Prep and Glassdoor; they show the level and style, not a fixed list.
| Track | Reported questions and topics |
|---|---|
| Analog design | RC circuit Bode plots and transients worked out by inspection. Current-mirror headroom, op-amp bandwidth limits, ADC and comparator choices. Diode V-I curve and breakdown voltage. Network analysis, BJT and MOSFET basics. |
| Digital design | Output of a chain of XOR gates. Draw CMOS, PMOS and NMOS structures. Mealy vs Moore machines and an FSM for a “101” sequence detector. Blocking vs non-blocking assignments, basic STA and Verilog. The digital section also covers ANSI C and 8085 basics. |
| Embedded software (intern) | Reverse the digits of an integer; reverse a hex number without using char. Trace loop and branch counts in a program. Array vs structure; build and reverse a linked list. The volatile keyword. Code a 3-state FSM in C. |
| Software engineer | Detect endianness in C. Read the contents of a 32-bit hex address. Cache coherence and cache invalidation. Memory alignment, and write an aligned_malloc(size, align) and its free. |
Asked across every track: a 20-40 minute walk through your CV and projects, “Why TI?”, and your career plans. TI’s software and embedded interviews are low-level C, OS and cache questions rather than DSA puzzles.
Written Test
A shared aptitude section (quant, logical reasoning) plus a section specific to your applied profile - analog electronics for Analog Design/Layout roles, digital logic and computer architecture for Digital/Embedded/Software roles. Campus drives (IIT Kharagpur FORESIGHT, IIT Guwahati, IIT KGP CDC reports) let you apply for up to two of four profiles - Analog, Digital, Embedded, Signal Processing - but you typically attempt one aptitude plus one or two profile-specific technical sections. CGPA 7.0 and ~60% in 10th/12th with no active backlogs are commonly cited eligibility gates - confirm your placement cell mail.
Some drives run this on HirePro (Software profile reports: MCQ-only, accuracy-weighted shortlist). Analog/Digital sections often stay within second-year ECE core - basic devices, RLC, Boolean logic, computer organization - phrased trickily rather than as graduate-level VLSI exams.
Common questions
- Quantitative and logical reasoning at a standard placement-test difficulty; permutations/combinations and probability appear in FORESIGHT aptitude accounts
- Analog section: RC/RLC circuit behaviour, op-amp basics, network theorems, device fundamentals
- Digital section: number systems, logic gates, MUX-based gate construction, sequential vs combinational, introductory computer architecture
- Embedded Software section (when selected): C pointers, bit manipulation, OS/RTOS MCQs - not a separate DSA coding contest on every campus drive
Full round-by-round breakdowns are on the Texas Instruments interview experience page.
Technical interviews: analog roles
For Analog Design and Analog Layout profiles, expect 1-2 rounds built around circuit intuition rather than memorised formulas. Interviewers commonly spend the first 20-30 minutes on your resume and projects before shifting into fundamentals, then go deep on whatever project you mention involves a real circuit.
Common questions
- First-order and second-order RC circuit response, explained by intuition rather than differential equations
- Poles, zeros, and current mirrors
- SAR ADC sampling capacitance and Flash ADC gray encoding
- Op-amp, MOSFET, BJT, and CMOS basics
- Deep-dive questions on any ADC, LDO, or converter project on your resume (power, comparator topology, redundancy)
Technical interviews: digital, embedded, and software roles
Digital Design, Firmware/Embedded Software, and general Software profiles get a different technical mix: embedded C, RTOS concepts, and computer-architecture fundamentals rather than analog circuit theory. Some panels open with 15-20 technical questions before ever opening your resume; others go project-first.
Common questions
- Endianness, pointer arithmetic, and memory alignment in C
- Cache coherence, SRAM vs DRAM, virtual memory basics
- RTOS concepts: task scheduling, priority inversion, semaphores/mutexes
- FSM design - including divide-by-3 counters with synchronous reset; blocking vs non-blocking Verilog for flip-flops
- Setup/hold time, clock skew, and introductory STA-style timing (Digital Design profile)
- CMOS inverter behaviour, propagation delay, and sequential circuit waveforms (ECE campus digital interviews)
- Bit-manipulation and OS fundamentals questions
Project presentation (experienced and specialised roles)
Some experienced-hire and specialised technical loops add a short prepared presentation - typically 15-20 minutes - where you walk a panel through a past project and then field follow-up questions on the choices you made, trade-offs you weighed, and results you achieved. This is reported less often in mass fresher/campus drives, where the same ground is usually covered conversationally inside the regular technical interview instead of a dedicated slot.
Common questions
- Why did you choose this approach over the alternatives you considered?
- What would you change if you rebuilt this project today?
- What data or measurements backed this design decision?
HR interview
A closing 20-30 minute round on motivation, TI’s business, and practical fit (location, notice period). Several candidate reports note that reaching this stage usually means the technical bar is largely cleared already.
Common questions
- Tell me about yourself?
- Why Texas Instruments?
- TI makes analog and embedded chips used across industries - what do you know about our product lines and where you’d fit?
- Walk me through a circuit or firmware project from your resume in detail?
- Are you willing to relocate to Bangalore or another TI hub?
Sample answer frameworks for each of these are on the Texas Instruments HR interview questions page.
Analog depth is the real differentiator
Unlike most software-company loops on this site, a large share of TI’s India engineering hiring is genuinely analog and mixed-signal - not embedded-adjacent software with a hardware label. If you’re targeting an Analog Design or Analog Layout role, DSA-style prep will not help much; the bar is circuit intuition (can you reason about a Bode plot or a current mirror out loud, not just recite the formula) plus the ability to defend a real analog project in detail. If you’re targeting Firmware/Embedded Software, the bar shifts to C fundamentals, RTOS, and computer architecture rather than analog theory - so confirm which track you’re interviewing for before you prepare.
TI analog vs digital vs embedded software tracks
TI does not run one common test and one common interview. You sit a shared aptitude section plus up to two track sections, and the track you clear decides which panel you meet. Candidates who prepare only general aptitude, or only DSA, are the ones most often caught out.
| Track | Test section covers | Interview focus |
|---|---|---|
| Analog | RLC circuits, network theorems, control systems, devices | Circuit intuition, op-amps, current mirrors, ADCs, analog projects |
| Digital | Logic, latches and flip-flops, ANSI C, 8085, timing slack | Gate-level circuits, CMOS, FSMs, Verilog, STA |
| Embedded / Software | C, OS, computer architecture | Live C coding, pointers, endianness, cache, RTOS |
This page covers all three tracks. Pick the two tracks that match your projects, since the interview will dig into them.
Common technical interview questions and answers
Q: Explain the step response of a first-order RC circuit by intuition rather than by solving the differential equation.
At the instant a step is applied, the capacitor voltage cannot change instantaneously, so it still holds its previous value and the full step appears across the resistor, giving the maximum initial current of the step amplitude divided by R. As charge accumulates, the capacitor voltage rises, the voltage across the resistor shrinks, and the current falls proportionally - so the rate of change is always proportional to how far you still have to go, which is what produces an exponential. The time constant is R times C: after one tau you have covered 63 percent of the gap, after three tau 95 percent, and after five tau you are within a percent. In the frequency domain the same circuit is a single-pole low-pass filter with a minus 3 dB corner at 1 divided by 2 pi RC, rolling off at 20 dB per decade with 45 degrees of phase lag at the corner.
Q: What is a current mirror and what limits its accuracy?
A basic current mirror is two matched transistors sharing a gate or base node, with the reference device diode-connected so its gate-source voltage is set by the reference current; the output device, seeing the same gate-source voltage, sources a proportional current set by the width ratio. Accuracy is limited first by channel-length modulation, since the output current depends on the output drain voltage through the finite output resistance, and second by random mismatch in threshold voltage and mobility, which improves as the square root of device area. A cascode mirror shields the input device from output voltage swing and raises output impedance by roughly the cascode transistor’s intrinsic gain, at the cost of headroom; a Wilson mirror uses feedback for similar benefit. For BJT mirrors there is an additional base-current error of about 2 divided by beta, which a helper transistor removes.
Q: How does a SAR ADC work, and how does it compare with a Flash ADC?
A successive-approximation ADC samples the input onto a capacitor array, then performs a binary search: the DAC is set to mid-scale, a comparator decides whether the input is above or below, that bit is latched, and the process repeats for each lower-weight bit - so an N-bit conversion takes roughly N comparator decisions and one clock each. That makes it moderate speed with excellent power efficiency and only one comparator, which is why it dominates 8 to 18 bit general-purpose converters. A Flash ADC instead uses 2 to the power N minus 1 comparators against a resistor ladder to resolve the whole code in a single clock, giving gigasample speeds but power and area that double with every added bit, which caps it near 6 to 8 bits. Pipeline converters sit between the two, and sampling capacitance in a SAR is set by kT/C noise and required settling, trading noise against input drive requirements.
Q: What is the difference between SRAM and DRAM?
An SRAM cell is a six-transistor cross-coupled latch that holds its value as long as power is applied, so it needs no refresh, has access times in the low nanoseconds, and is used for caches and register files - at the cost of large area and higher static leakage. A DRAM cell is one transistor plus one capacitor, so it is far denser and cheaper per bit, but the charge leaks away and must be refreshed every few tens of milliseconds, and reading is destructive so the sense amplifier writes the value back. DRAM access is also slower and has row-activate, column-access, and precharge timing constraints, which is why memory controllers reorder requests to exploit open rows. That density-versus-speed split is exactly why systems use an SRAM cache hierarchy in front of DRAM main memory.
Q: What is endianness, and how would you detect it in C?
Endianness is the byte order used to store a multi-byte scalar in memory. Little-endian machines, such as x86 and most ARM configurations, place the least significant byte at the lowest address; big-endian machines, common in network protocols, place the most significant byte first. Detect it by writing a known value and reading it back through a narrower type: set uint32_t x equal to 1, then take unsigned char p equal to the address of x cast to unsigned char pointer - if p[0] is 1 the machine is little-endian. It matters whenever bytes cross a boundary, which is why network code converts with htonl and ntohl, and why casting a byte buffer straight to a struct pointer is unportable and can also violate alignment requirements.
Q: What is priority inversion and how does an RTOS solve it?
Priority inversion happens when a high-priority task blocks on a mutex held by a low-priority task, and a medium-priority task that needs no such lock preempts the low-priority holder - so the high-priority task waits indefinitely on a task it outranks. The Mars Pathfinder resets in 1997 are the canonical field example. Priority inheritance fixes it by temporarily raising the lock holder’s priority to that of the highest waiter, so the holder cannot be preempted by a medium-priority task and releases the lock promptly. Priority ceiling protocol goes further by giving every mutex a static ceiling priority assigned on acquisition, which additionally prevents deadlock and bounds blocking to a single critical section - most commercial RTOS kernels offer inheritance as a per-mutex option.
Q: What is the difference between a semaphore and a mutex?
A mutex enforces mutual exclusion and has ownership - only the task that took it may release it - which is what lets the kernel implement priority inheritance and detect recursive misuse. A semaphore is a counting signal with no owner: any task may give it, so it is the right primitive for signalling between an ISR and a task, or for limiting concurrent access to a pool of N identical resources. Using a binary semaphore where a mutex belongs is a classic embedded bug, because it silently discards priority inheritance and permits one task to release a lock another task holds. Also remember that a task must never block on a mutex inside an interrupt service routine - you signal a semaphore from the ISR and do the work in a task instead.
Q: Count the number of set bits in an integer efficiently.
The naive loop shifts right and tests the low bit 32 times regardless of the value. Brian Kernighan’s method is better: repeatedly do n equal to n AND (n minus 1), which clears the lowest set bit each iteration, so it loops only as many times as there are set bits. A lookup table over bytes gives a fixed four table reads for a 32-bit word, and most modern instruction sets have a single popcount instruction that compilers emit for the intrinsic. Watch two portability traps: right-shifting a signed negative integer is implementation-defined and can shift in ones forever, so use an unsigned type, and shifting by the full width of the type is undefined behaviour.
Q: Design a divide-by-3 counter using an FSM (Digital campus classic).
Use a state register with three states (0, 1, 2) and output a tick when returning to state 0 from state 2, or output a pulse every third clock depending on the spec. Draw the state diagram first, then write next-state logic: on each clock, advance 0→1→2→0. In Verilog, prefer synchronous reset and non-blocking assignments for sequential logic unless the interviewer asks for a latch-based discussion. Campus panels often follow with timing: can you meet setup time if the combinational next-state logic is long?
Q: What are setup time and hold time?
Setup time is how long the data input must be stable before the active clock edge so the flip-flop can latch reliably; hold time is how long data must remain stable after the edge. Violate setup and you get metastability or wrong captures; violate hold and the previous bit may leak through. Clock skew between launch and capture flip-flops eats into the effective setup budget - STA tools exist to verify margins. Digital TI interviews expect you to sketch timing on waveforms, not only recite definitions.
Q: Explain a CMOS inverter when the input switches (ECE digital interview).
With input low, the NMOS is off and PMOS on, pulling output toward VDD; with input high, PMOS off and NMOS on, pulling toward ground. During transition both devices may conduct briefly, causing shoot-through current; gate capacitance dominates switching energy. Interviewers ask what happens to output voltage and current as input crosses the threshold - link to propagation delay and why fan-out matters.
Frequently asked questions about Texas Instruments interviews
Does the Texas Instruments online test have negative marking?
Yes, on most reports. A digital-design candidate gives the marking as +1 for a correct answer and -0.25 for a wrong one, and FACE Prep notes negative marking in the aptitude section; some write-ups do not mention it, so check the instruction screen of your own test.
What is the cutoff for the Texas Instruments online test?
TI does not publish one. Each section is reported to have its own cutoff, which FACE Prep puts around 55-60%, and eligibility is usually 7.0 CGPA with about 60% in 10th and 12th and no active backlogs. The test is on HirePro and has no coding questions.
What is the Texas Instruments interview process for freshers?
TI India campus hiring (mostly out of the Bangalore Design Centre) runs 3 stages: a Written Test (aptitude plus a profile-specific analog or digital electronics section), 1-3 Technical Interviews (roughly an hour each, usually starting with CV/project discussion before moving into circuit theory, embedded C, or RTOS questions depending on the role), and a final HR Interview. Some analog and hardware roles add a short project-presentation component where you defend design choices to a panel.
What questions are asked in Texas Instruments interviews?
Questions split hard by role. Analog Design/Layout candidates get op-amps, MOSFETs, current mirrors, RC/RLC transient behaviour, ADC architectures (SAR, Flash), and network theorems. Digital/Embedded and Firmware/Software candidates get embedded C (pointers, memory alignment, endianness), RTOS concepts, cache/SRAM-DRAM basics, and CPU/SoC architecture. Every technical round typically opens with 20-40 minutes on your resume and projects before shifting to core concepts.
How many rounds are there in the Texas Instruments interview?
Typically 3-4 touchpoints: a Written Test, one to three Technical Interviews (often over Webex, with screen share), and a final HR Interview. The exact number of technical rounds depends on role, campus, and whether you’re hired as an intern or full-time engineer.
Does Texas Instruments hire for analog design or software engineering in India?
Both, and the split matters more at TI than at most software-first companies. TI is fundamentally an analog and embedded semiconductor company, so its India roles include Analog Design/Layout Engineer, Digital Design Engineer, Firmware/Embedded Software Engineer, Applications Engineer, and Test Engineer - alongside a smaller number of pure software roles (tools, infrastructure, data). Check the exact job description before assuming your prep should be DSA-heavy.
How should I prepare for Texas Instruments interviews?
Match your prep to the role: revise core circuit theory (RC/RLC, network theorems, op-amps, ADC basics) for analog roles, or embedded C, RTOS, and computer-architecture basics (cache, memory alignment, endianness) for embedded/firmware roles. For every role, be ready to explain any project on your resume in real depth - TI panels probe projects harder than most fresher interviews, sometimes for 30-40 minutes on a single project.
Is there a project presentation round at Texas Instruments?
For some experienced-hire and specialised roles, yes - candidates report preparing a short (15-20 minute) technical presentation on a past project, then defending design choices, trade-offs, and results in front of a panel. This is less common in mass fresher/campus drives, where project discussion is folded into the regular technical interview instead of a separate presentation slot.
What is the reported salary for Texas Instruments freshers in India?
Community-reported figures (AmbitionBox, Glassdoor, 6figr) put fresher CTC roughly in the ₹14-25 LPA range depending on role and campus tier, with embedded/firmware and analog roles often at the higher end. These are self-reported aggregator numbers, not official TI figures - always confirm against your actual offer letter.
How to prepare for Texas Instruments interviews
- Loop map: Written Test; Technical Interview(s); Project presentation (some roles); HR Interview. Confirm timings from the drive mail.
- Technical depth: Drill the Q&A section until answers are spoken, not read. Know every resume project cold.
- Experiences: Study round-wise notes on the interview experience page - real prompts beat generic lists.
- HR: Three STAR stories + a specific “Why Texas Instruments?” on the HR page.
Who usually fits and who struggles
Good fit: You can sketch a first-order RC transient without writing a differential equation. You can walk an ADC project from sampling capacitor to comparator kickback. Or, for Embedded, you can write endian-aware C and talk cache lines. You picked two profiles and ignored the third.
Harder path: You only watched Razavi playlists and never solved a numerical. You guess on aptitude (negative marking). You claim Analog interest but cannot open your own lab report. A 9.0 with shallow projects loses to a 7.2 who lived in the ADC schematic.
A practical Texas Instruments prep plan
Use this as a default four-week loop before a Texas Instruments drive. Adjust to your invite timeline.
- Week 1: Language fluency: rewrite 10 old solutions in one language until you stop hunting syntax. Open the Texas Instruments previous-year sets on this site and mark which sections ate your time. Write the timing on a sticky note. That number is more useful than a 200-problem LeetCode streak you never timed.
- Week 2: Most Texas Instruments drives fail people on the first timed paper or OA. Do three timed sits this week. After each one, log every miss in a two-column note: topic and why (slow, wrong formula, bad edge case, panic). The next sit should only add problems from that log.
- Week 3: Technical interviews at Texas Instruments usually want a clean project story, one or two CS fundamentals, and (if the process has it) a behavioral or values round. Write STAR stories on paper, not in your head. Practise “Why Texas Instruments?” with one concrete product, lab, or business line - not a slogan.
- Week 4: Sleep, id photocopies, and a dry run of the oa platform if the invite names one. If you still have energy, redo only the questions you failed in week 2.
10-day crash version: Days 1-4 timed DSA, days 5-7 resume projects + CS fundamentals, days 8-9 mock interviews out loud, day 10 HR STAR stories on the HR page.
Compensation notes
Candidate-reported fresher/early-career packages for Texas Instruments often cite ₹14-25 LPA. Treat forum numbers as ranges, not guarantees - confirm the written offer letter for your team and location.
