AT&T candidates in 2025 describe a HackerRank-first process for engineering and an assessment-first process for stores. Technology Development Program candidates took a HackerRank OA (one had four questions in an hour, including SQL), a behavioral screen, a technical interview with LeetCode-style coding and a debugging exercise, and a behavioral final. Retail Sales Consultant candidates took an online assessment, then a phone screen and a store or panel interview built around a sales role-play. Hyderabad campus candidates reported project-heavy technical rounds.
TDP candidates who got offers mostly called the coding easy to medium; those who did not rarely said why. The longest waits were in the TDP, which Glassdoor puts at about 60 days on average.
AT&T interview process round by round
| Round | Duration | What it tests |
|---|---|---|
| Online assessment | about 45-60 min (CSAF); about 1 hour (TDP HackerRank) | Situational judgment, or coding and SQL |
| Phone screen | not published | Behavioral questions, location preferences |
| Technical interview (TDP) | about 1 hour | LeetCode-style coding, debugging, some system design |
| Behavioral final | up to 1 hour | Coworker disagreement, strongest skill, presenting unprepared |
| Store or panel interview | not published | Sales role-play, customer stories |
| Offer | varies | Background check, drug screening for some roles |
AT&T interview reports from 2025
Each is one candidate’s account, paraphrased.
- TDP Software Engineer, Dallas, TX (February 2025, Taro, offer accepted).

- TDP Software Engineer, Bothell, WA (September 2025, Taro, offer accepted). A medium-to-hard OA, an HR call, a technical interview with easy LeetCode-style questions, and a behavioral interview asking about their strongest skill and a time they presented on a topic they had not prepared for. About 3 to 4 weeks; each interview 30 to 60 minutes.

A technical round on resume, projects, communication and handling pressure, including how to deploy a project and handle production traffic while developing in parallel, then an HR and managerial round. The candidate called it standard but long.

Detailed interview experiences
Experience 1: TDP Software Engineer, Dallas, February 2025
Profile: New graduate; offer accepted.
OA: HackerRank with a few coding questions.
Screen: Three or four behavioral questions and a discussion of which TDP cities the candidate would accept.
Technical: Two LeetCode-style questions, then a debugging exercise on given code, then system design questions.
Final: One hour with an associate director, all behavioral, including a time you disagreed with a coworker.
Takeaways
- Decide your location preferences before the screen; the program requires being in the posted city five days a week.
- Practice debugging someone else’s code aloud, not only writing new code.
Experience 2: TDP Software Engineer, Bothell, September 2025
Profile: New graduate; offer accepted in 3 to 4 weeks.
Rounds: OA rated medium to hard, an HR call, an easy coding interview, and a behavioral interview. Each interview ran 30 to 60 minutes.
Behavioral questions: Your strongest skill, and a time you had to present on a topic you were not prepared for.
Takeaways
- The OA was the hardest step; the live coding was easier.
- Prepare a story about presenting under short notice.
Experience 3: Retail Sales Consultant, store loop
Profile: Store candidates from Glassdoor reports and The Interview Guys’ retail guide.
Assessment: Right after applying, role-specific and scored before any recruiter call.
Interviews: A phone or video screen, then an in-person or group panel interview. Questions such as “if I walked in as a customer, what would you sell me,” why you would be a good fit, and on-the-spot pitches for an iPhone or a fiber plan.
After the offer: Background check and drug test; one candidate had to complete the drug test within 24 to 48 hours.
Takeaways
- Learn AT&T’s current plans and fiber tiers before the interview.
- Ask the “customer” questions before pitching.
Experience 4: Senior Associate Software Engineer, Hyderabad campus, September 2025
Profile: Final-year student in an on-campus drive; offer accepted.
Technical round: In person. Resume and projects in depth, communication, and how the candidate handles pressure. The named question: how would you deploy one of your projects and handle production traffic while continuing development.
HR and managerial round: Standard questions; the candidate did not list them.
Takeaways
- Know how your own project would run in production: hosting, load, rollbacks.
- Expect a long day; the candidate called the process standard but lengthy.

AT&T interview tips from these reports
HackerRank OA
- Expect SQL alongside coding; one Dallas OA had a basic SQL question in four.
- Some reports describe camera-on proctoring.
TDP interviews
- The technical round pairs live coding with a debugging exercise.
- Behavioral finals can run an hour with an associate director.
Retail
- Role-plays ask what you would sell the interviewer; ask questions first.
- Drug tests may need to be done within 24 to 48 hours of the offer.
