Round 1 APTITUDE + CODING TEST The first round comprised of a total of 32 Questions (30 Aptitude + 2 Coding) The aptitude part was dominant as most of the questions were based on Data Interpretation(Graphs, Pie charts etc.) and demanded good time management. For the 30 aptitude questions the time allowed was 30 minutes. The coding questions were really easy to solve. 30 minutes for 2 coding questions and I was able to solve both of them in under 10 minutes. Question 1: To check if numbers at even indices of an array were even or not. Question 2: Tomohiko Sakamoto's Algorithm: https://www.geeksforgeeks.org/dsa/tomohiko-sakamotos-algorithm-finding-day-week/ Out of 200 students 8 were shortlisted because of the difficulty level of the aptitude test and I was lucky enough to get through.
Round 2 TECHNICAL INTERVIEW The interview was resume based and most of the questions asked were based on my projects and the technologies that I had worked on. The interview was 50 minutes to 1 hour long. After exploring my projects the interview asked me about basic Data structures and OOPS concepts like polymorphism, Exception handling in JAVA, connections in JDBC. In the end I just asked him about his experience at UHG and this was the end of my technical interview. After this I was shortlisted for the managerial round.
Round 3 MANAGERIAL ROUND If you've got through the first 2 rounds then this confirms 90% of your chance of selection. In this round questions about my hobbies were asked. Common managerial questions like: 1.Where do you see yourself in 5 years? 2.How would you manage a given situation at the office? 3.Biggest achievement in your life? 4.Strengths and weaknesses? and things like that. This was a 15 minute interview and I was shortlisted for the HR round.
Round 4 HR Round. This round had 2-3 questions about my family background and my job location preference. This interview lasted around 5 minutes and then the final decision was given. Out of the 8 shortlisted candidates 4 were selected.

About United Health Interview Reports
This question was reported by a candidate who interviewed at United Health. LeakCode aggregates interview reports from 10+ sources, including 1Point3Acres, Glassdoor, LeetCode Discuss, Blind, Reddit, Indeed, and Nowcoder. Each report is translated where necessary, deduplicated against existing entries, and tagged by company, role, round type, and reporting date.
Use this question as one calibration data point, not a memorization target. Companies typically rotate their question pools every 2-4 months; the exact wording of a 2024 question may differ from what you encounter today. The underlying pattern, difficulty level, and follow-up depth at United Health are the higher-signal extractions to take from this report.
For broader preparation context, the United Health interview process typically includes a recruiter screen, one or two technical phone screens, and a 4-5 round on-site loop covering coding, system design (at L4+ levels), and behavioral. Reports tagged on LeakCode show the round-by-round distribution and typical difficulty calibration. To browse questions filtered by round type and seniority, use the company hub linked above.
How To Practice This Type of Question
Solve similar problems on LeetCode under timed conditions (25-35 minutes per medium difficulty). The goal is pattern recognition: recognize the underlying technique (sliding window, two-pointer, BFS, memoized recursion, etc.) within 60-90 seconds of reading. Strong candidates verbalize their hypothesis out loud before coding, then iterate based on feedback. Weak candidates dive into implementation immediately, lose time on the wrong approach, and run out of time for follow-ups.
Companies update their question pools every 2-4 months. The exact wording of any given question may have been retired by the time you interview. Focus your prep on the pattern, not the specific problem. The patterns that appear in United Health reports consistently are the ones worth investing in; one-off niche problems are not.
During Your United Health Round
Apply the standard interview round template: clarify requirements (2-3 minutes), state your approach out loud and confirm direction with the interviewer (3-5 minutes), code with narration (15-25 minutes), test with concrete examples including edge cases (5 minutes), discuss optimization or trade-offs if time permits (5 minutes). This template is universally accepted across FAANG and adjacent companies; deviating from it produces weaker interviewer feedback signal.
The single most predictive failure mode in United Health reports tagged "no hire": not asking clarifying questions. Interviewers are explicitly trained to weight this. Strong candidates ask 3-5 clarifying questions even on problems that look obvious; weak candidates dive into code immediately. The clarifying-question check is often the first signal recorded in the interviewer's written notes.
