Full Details
I belong to a tier-3 college. I applied for the SDE position through referral, and luckily I got the test link. Each round started with my introduction and all the interviewers were quite supportive. I was able to solve all questions with their best Time Complexity. Round 1(Online Round, 90 minutes) It was a test on the Hackerrank platform and comprises 6 questions. Three questions were based on the Data Structures and Algorithm and the remaining ones were on SQL query. I was able to solve the 2.7 questions of DSA and one question of SQL. Round 2(Technical Interview, 90 minutes) Two questions of DSA were asked which were:- https://www.geeksforgeeks.org/dsa/search-in-row-wise-and-column-wise-sorted-matrix/ Merge sort for linked list (This question wasn't asked directly) One SQL Question- One SQL question was asked to find the person from the table (two tables were given) who has placed the maximum orders. I was able to solve both of the DSA questions optimally but wasn't able to write the SQL query (although I told him the approach) Round 3(Technical Interview, 90 minutes) This interviewer was more interested in my solution approaching skills. He asked me a question based on DSA in which there were 6 knights, and they were in a circle. Each knight has a power of 100 initially. Every knight kicks the knight who is in front of him with any random power. We need to find the last surviving knight (similar to https://www.geeksforgeeks.org/dsa/josephus-problem/ ). This was a new question for me, but I was able to code it. One more coding question was asked. Apart from DSA, he asked me questions related to OS, Projects, DBMS, and questions like why do you want to be a Software Engineer, why CS when I am from ECE. Round 4(Technical Interview, 90 minutes) Two questions were asked based on DSA:- https://www.geeksforgeeks.org/dsa/search-an-element-in-a-sorted-and-pivoted-array/ Find the longest path having maximum sum from leaf to leaf and containing the root. I was able to solve this problem recursively and She was quite satisfied with the approach and then I coded it. One SQL Question SQL question which was to basically check if the given directory is correct or not. A table was given which had all the details. (I was able to give her the approach) Round 5(Technical + MR, 60 minutes) This was the last round and one of the Senior managers took my interview. He was a quite helpful person. He asked me my favorite question from the previous rounds, then he switched to JAVA OOPS, OS, DBMS, Projects, and some basic SQL questions. After a week, I received the offer letter & joining letter for the FTE + INTERN. If you want to get into UHG then you should be able to write SQL queries but If you have good coding skills but average SQL knowledge (like me :P) then you'll be able to make it to the end.

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.
