Across 16 candidate reports, the most consistent theme is a HackerRank-style online screen followed by technical rounds that lean on Java, OOP and your own resume projects. Coding problems are often described as easy to medium. Examples include summing or minimizing an array, anagrams, palindromes, a path-sum binary tree problem, and a LeetCode-style pair-sum question.
Several candidates say interviewers spent real time on past projects, architecture choices and trade-offs. Be ready to explain why you built something the way you did, not only what it does. Java topics reported include how HashMap works, Streams, multithreading, Spring Boot, and int versus Integer. SQL questions such as the second or nth highest salary, joins and window functions also come up. A few reports mention puzzles, including the 25 horses problem and a water-bucket problem.
The format varies a lot by role and location. Reported processes range from three rounds to six or seven, and some candidates describe a director, hiring manager or HR conversation near the end. Senior candidates report system design tied to their own work, with an ATM design problem mentioned once. Two Python-focused reports covered type hinting, immutable types and API testing, and one Senior report covered Kubernetes components. Several candidates say communication and confidence mattered. A few describe disorganized scheduling or no feedback after rejection. Treat the timeline as unpredictable.

Real interview reports from people who went through the Ukg process.
The interview process was pretty structured and ended up being more of a resume-and-fundamentals grilling than anything exotic. I went through five rounds total: an online coding test on HackerRank, then three technical interviews, followed by a hiring manager round and an HR round. In my case the technical portion was the bulk of it, and the questions stayed mostly at a basic to intermediate level. A lot of the discussion centered on OOPS, DSA, and core concepts, with strings coming up more than once. I was also asked to sort an array in a specific order, and there were questions around design patterns I had worked with. The coding test itself was described as really technical, and the pair-coding style round felt more like applying software skills to a real-world problem than solving a pure algorithm puzzle.
What stood out most was how much they cared about honest, straightforward answers and how closely they dug into projects on the resume. One round felt like pure resume grilling, with architectural questions about past work and a few puzzles mixed in. The behavioral side was lighter but still present, including a question about a time I had to meet a hard deadline. Overall the process took a while, but the decisions were made on time. I ended up getting an offer, and my main takeaway was that this interview rewards solid fundamentals, clear explanations of your own projects, and being comfortable talking through basic Python and JSON-related concepts if the role calls for it.
Prep tip from this candidate
Focus on basic OOPS and DSA questions, especially strings, and be ready to explain your projects and design-pattern choices in detail. It also helps to practice a HackerRank-style coding test and a pair-coding round that feels closer to a real application than a textbook algorithm problem.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report a recruiter or phone screen, sometimes with basic behavioral questions, followed by a HackerRank assessment. Reported content ranges from one or two easy DSA problems to three medium questions. Intern-level reports mention multiple-choice questions on databases, networks and OOP. Timelines for completing it vary by report.
Several candidates describe a first technical round mixing live coding with fundamentals. Reported topics include strings and arrays, trees, HashMap internals, Streams, Collections, OOP and SQL. Senior candidates also mention two LeetCode medium problems. Interviewer engagement reportedly varied, so expect to explain your reasoning clearly.
Many reports describe interviewers digging into resume projects: technical decisions, trade-offs and challenges. Senior candidates report system design tied to past work, and one mentions an ATM design question. Prepare to defend your choices and discuss how you would scale or change what you built. Python-focused roles may go deeper on language features.
Reported final stages include a hiring manager conversation, a techno-managerial round, a director interview and an HR discussion covering culture, hybrid work or compensation. Questions touch on deadlines, conflicts and why you want to join or leave your current employer. Candidates say communication and rapport mattered. Some report an additional round added late, or no feedback after rejection.
