Optum Interview Experience 2026

How Optum (UnitedHealth Group) campus SDE loops actually run: clear fundamentals and easy-medium DSA more than exotic system design. Synthesized from recent candidate reports with rounds reorganized and prep notes added - treat this as a prep map, not a script.

Round-wise process at a glance

Round Typical format What clears you
OA Mettl/HirePro ~90 min: aptitude + CS MCQs + 1 code Optimised code when required
HR / behavioural 15-20 min (sometimes first) Communication
Technical 25-50 min: projects, DBMS, SQL, DSA Two Sum-level hash + SQL

Technical interview experience 1 - SDE TDP On-Campus 2023 (selected)

Technical interview experience 1

Candidate profile: SDE TDP; Gurgaon/Hyderabad. Source: GeeksforGeeks Optum UHG SDE TDP On-Campus 2023.

Round 1 - Mettl OA (90 min)
  • 1 graph coding question
  • Cognitive ability + analytics sections
  • 25 technology / CS fundamentals MCQs
  • Same-day shortlist: 41 to interviews
Round 2 - HR first (15-20 min)
  • All shortlisted advanced to technical in that account (not a universal rule)
Round 3 - Technical (45-50 min)
  • Intro + projects
  • DBMS: normalisation why; MySQL type; table relationships
  • Live SQL on notepad (student/class style schema)
  • Language preference → code Two Sum (brute then optimised hash)
  • Final result: Selected (14 offers next morning in that report)

Key takeaways: Expect HR/tech order flips; notepad SQL + classic Two Sum still decide offers.

Takeaways

  • What decided it: Optimised OA code when required, plus notepad SQL and Two Sum-level hashing with complexity stated
  • Common fail: Fancy HLD prep while failing handwritten SQL; freezing if HR comes before tech
  • How to practise: Mettl-style mocks; JOIN queries on paper; hash-map mediums with Big-O aloud

Technical interview experience 2 - Full Stack / NIT KKR SDE

Technical interview experience 2

Candidate profile: Composite of HirePro full-stack 2022 + OPTUM-UHG NIT KKR 2022.

OA
  • HirePro: aptitude/verbal + CN/DBMS/OS/DSA MCQs + coding (subsequences with target sum - brute accepted in one account)
  • Mettl alternate: 50 Q (1 medium DP coding + 49 DBMS/OOP/SQL/aptitude MCQs)
Technical
  • Python list/dict easies; OOP inheritance; interface vs abstract; MySQL queries
  • Normalisation forms (admit gaps honestly if ECE)
  • NIT account: icebreaker on social topic → second largest in array + TC/SC; OOP for non-tech person; ML/optimisation if resume; projects + internship
HR
  • Intro; strengths/weaknesses; what excites about Optum; project chat; perks/locations
  • One full-stack report: 61/121 to HR with near-full HR conversion claimed
  • Final result: Selected on successful accounts

Key takeaways: Explain OOP with analogies; healthcare domain interest helps but is not a quiz on US health policy.

Takeaways

  • What decided it: Clear OOP analogies and project ownership without pretending to know US health-policy trivia
  • Common fail: Overclaiming healthcare domain expertise; weak fundamentals after a smooth HR chat
  • How to practise: OOP with everyday analogies; one project trade-off story; short PPT-based question ready

HR interview experience

HR interview experience

Candidate profile: Selected TDP / SDE

HR themes
  • Why Optum / UHG; location (Gurgaon/Hyderabad)
  • Strengths and weaknesses
  • Higher studies plans
  • Final result: Offer when cleared

Key takeaways: Keep answers short; ask one PPT-based question back.

Campus interview experience 3 - TDP Associate, VIT 2024

Candidate profile: Technology Development Program - Software Engineering Associate; Hyderabad or Gurgaon. Source: GeeksforGeeks Optum Interview Experience 2024 TDP Associate (VIT).

Round 1 - Mettl OA (90 min, proctored)
  • CGPA gate: 7.0+; 402 candidates took the test; 72 shortlisted
  • 50 MCQs: logical, quantitative, abstract reasoning, technology (OOP, DBMS, basics)
  • 1 coding question - DP-style, medium difficulty; optimised solution expected
Round 2 - HR (10–15 min)
  • Behavioral cultural-fit screen before technical in this batch
  • Short intro; motivation for Optum / healthcare technology
Round 3 - Technical (40–45 min)
  • Self-intro; resume project with demo and cross-questions
  • Real-world scenario prompts (problem-solving, not trivia)
  • Final result: Selected (process described as transparent on role scope)

Key takeaways: HR-before-tech happens on some campuses; know one project cold enough to demo and defend tradeoffs.

Campus interview experience 4 - Software Engineer-1 (three-round composite)

SE-1 on-campus composite

Candidate profile: Composite of GeeksforGeeks Oct 2024 Optum experience and papersadda summary of SE-1 three-round pattern.

Round 1 - OA
  • Aptitude + technical MCQs (OS, DBMS, programming)
  • One medium DSA problem - brute force insufficient in reported account
Round 2 - HR / behavioral
  • Why Optum; explain a project without technical jargon
  • “How would you teach programming to a young child?” - tests simplification
Round 3 - Technical
  • OS and DBMS fundamentals; resume deep-dive
  • DSA with narrative wrapper; C++ STL usage and time complexity follow-ups
  • Final result: Selected on successful accounts

Key takeaways: Plain-language communication is scored in HR, not only in the closing HR round on other drives.

Off-campus interview experience - UHG Optum SDE

Off-campus multi-technical

Candidate profile: Off-campus SDE loop. Source: GeeksforGeeks UHG (Optum) Interview Experience Off-Campus.

Reported pattern
  • Online screen then multiple technical rounds (DSA + SQL heavier than some campus loops)
  • Pair sum, reverse linked list, triplet / tree distance style problems cited
  • Projects grilled for production thinking
Outcome context
  • Timelines stretch 2–6 weeks in many reports
  • Final result: Varies by team and level - treat as prep signal, not a guarantee of the same round count

Key takeaways: Off-campus candidates should budget extra DSA depth and SQL notepad practice beyond campus OA prep.

Sample answers for high-frequency questions

Technical

Q. Two Sum optimised?
A. One-pass hash map of value→index; check target - x before insert. O(n) time. Clarify duplicate index rules.

Q. Second largest in array?
A. One pass track largest and second; handle duplicates and length < 2. State O(n)/O(1).

Q. Explain OOP to a non-tech person?
A. Cars as objects sharing a Vehicle blueprint; encapsulation as dashboard hiding engine; inheritance as ElectricCar extending Car.

HR

Q. Why Optum?
A. Technology at healthcare scale (UHG); map your stack to reliable systems; one PPT fact.
