Publicly documented UnitedHealth Group interview experiences come almost entirely from its Optum technology arm in India, where the loop is a short, campus-style funnel: a timed online assessment mixing aptitude, CS-fundamentals MCQs and one or two coding problems, then one or two technical conversations built around the candidate's own projects plus data structures, SQL/DBMS and OOP, then a short HR or managerial chat that is often close to a formality. Experienced-hire and off-campus loops stretch the same shape out to four or five rounds with more SQL, tree/hashing problems and a light design-flavoured discussion at the end. For the far larger non-technical side of the company (nursing, claims, actuarial, corporate), the only thing that could be verified from permitted sources is UnitedHealth Group's own description of its process, which centres on recorded digital video interviews reviewed by humans, plus live virtual or in-person rounds with the hiring team.

UnitedHealth Group’s official process
UnitedHealth Group says its interviews come in three shapes: in person at an office, clinic or event; a live virtual conversation over video; and a digitally recorded interview where candidates answer preset questions on their own. For the recorded format the company states there is an unlimited-practice question, roughly three minutes per answer with a visible timer, up to three re-records per question, and that responses are reviewed by people rather than AI. It notes some interviews may also include an assessment, without saying which, and a companion page adds that a recorded interview may be shared with several teams to speed up review. The rest of the page is generic advice (research the mission and values, prepare examples and questions, test your tech, send a thank-you note).
Timed online assessment: aptitude, logical and verbal reasoning·CS fundamentals MCQs: OS, DBMS, computer networks, OOP·One easy-to-medium coding problem (arrays, strings, subsequences, graphs)·Data structures and algorithms in the interview: sorting, hashing, linked lists, binary trees·SQL query writing and DBMS concepts (normalization, indexing, joins, grouping)·Deep questions on the candidate's own resume projects·Explaining a technical project to a non-technical audience·Standard HR/behavioural: why Optum, strengths and weaknesses, location flexibility·Recorded (asynchronous) digital video interview for non-technical roles

Seniority
Software Engineer 1 (Optum)
New grad
Received an offer3 rounds
1
Online assessmentOnline assessment
A timed test blending aptitude questions with technical multiple choice on OS, DBMS and programming basics, closing with one medium data-structures problem where the candidate was expected to move past a naive solution.
A conversational HR round covering the usual motivation and self-assessment ground, plus a request to describe the candidate's project without technical jargon and an off-beat prompt about teaching programming to a small child.
Covered · Motivation, Strengths and weaknesses, Explaining projects simply
3
TechnicalTechnical
A longer technical conversation starting from the resume and projects, moving into core CS theory, then a LeetCode-medium style coding problem and follow-ups on which C++ data structure fits which situation and why.
Covered · Resume projects, OS, DBMS, Medium DSA problem, C++ containers and complexity, Engineering best practices
A two-hour test split evenly between algorithm problems and SQL problems, described as medium difficulty.
Covered · Data structures and algorithms, SQL
2
Technical interview 1Technical
Introductions and a walk through previous work, then object-oriented theory and database internals questions.
Covered · Prior work experience, Data structures, OOP (polymorphism, virtual functions), DBMS indexing and scheduling
3
Technical interview 2Technical
Hands-on problem solving on arrays and linked lists, including a frequency-counting question over a very large dataset that pushes toward a hash-based solution, plus more SQL.
Covered · Arrays, Linked lists, Set operations, Hashing at scale, SQL
4
Technical interview 3Technical
A tree-focused round with a couple of classic binary-tree problems and two easier warm-ups.
Covered · Binary trees, Lowest common ancestor, Node distance
5
Managerial / behaviouralHiring manager
A manager round mixing motivation and career-change questions with breadth checks on networking and compilers, ending in an open design discussion about modelling a spreadsheet's rows and columns.
Covered · Career transition, TCP vs UDP, Compiler basics, Design a spreadsheet-like structure
Software Development Engineer, Technology Development Program (Optum)
New grad
Received an offer3 rounds
1
Online testOnline assessment
A 90-minute test with a single graph-based coding question alongside large cognitive-ability, analytics and CS-fundamentals MCQ sections; only a small fraction of the cohort moved on.
A short 15 to 20 minute screen about motivation, teamwork friction and willingness to relocate; per the candidate, essentially everyone in this round advanced.
Covered · Company knowledge, Team conflict, Location preference, Explaining tech to non-tech people
3
Technical interviewTechnical
A 45 to 50 minute round anchored in databases, including writing a grouping query with a count threshold, then a classic pair-sum coding question where the interviewer wanted both the brute-force and the optimised approach.
Covered · DBMS normalization, SQL grouping and aggregation, MySQL data types, Two-sum style problem
A 90-minute, 50-question multiple-choice test spanning analytics, cognitive ability and technology topics, rated easy to medium.
Covered · Statistics, Graphs, Data structures, OS, OOP, SQL, Java
2
Combined technical and HRTechnical
A single 30 to 45 minute session that began with the candidate's web-development project, moved through sorting theory and a quicksort implementation, touched OS and SQL, then finished with HR-style questions about location and long-term plans.
Covered · Resume and web projects, Sorting algorithms and quicksort, Basic DSA, OS concepts, SQL queries, Location and future plans
A HirePro-hosted test combining aptitude and CS-fundamentals sections with one easy subsequence coding question; well under a third of the 400-plus cohort cleared it.
Covered · Aptitude, Reasoning, Verbal, Computer networks, DBMS, OS, DSA, One easy coding problem
2
Technical interviewTechnical
A brisk 20-minute round of project discussion and small Python coding tasks plus SQL; the candidate could not answer normal forms beyond 2NF and still advanced, so partial failure was clearly not disqualifying.
Covered · Projects, Python lists and dictionaries, OOP, MySQL queries, Normalization
3
HR interviewBehavioral
A brief closing conversation that the candidate described as a formality, with everyone who reached it receiving an offer.
A HackerRank test with two data-structures coding questions plus multiple choice on operating systems and databases; the candidate solved one problem fully and one partially and still progressed.
Covered · Two DSA coding problems, OS MCQs, DBMS MCQs
2
Technical interviewTechnical
A 45-minute round that ran from project discussion into a counting-paths coding problem, then breadth questions on cloud services and Python language semantics.
Covered · Projects, Stair-climbing / combinatorial coding problem, AWS and cloud basics, Python mutability, OS
A one-hour CoCubes test of 30 aptitude MCQs plus two coding questions, one a date-arithmetic problem and one formula-driven; roughly 20 candidates advanced.

What topics does UnitedHealth Group test in interviews?
Commonly reported topics include Timed online assessment: aptitude, logical and verbal reasoning, CS fundamentals MCQs: OS, DBMS, computer networks, OOP, One easy-to-medium coding problem (arrays, strings, subsequences, graphs), Data structures and algorithms in the interview: sorting, hashing, linked lists, binary trees, SQL query writing and DBMS concepts (normalization, indexing, joins, grouping), Deep questions on the candidate's own resume projects.
These guides summarize public, first-hand interview experiences shared by candidates. They describe the shape of each loop and the topics that came up, not a leaked question bank, and every experience links back to its original source. Processes change often.
