2 hr Coding round which was based on Data structure and Algorithms and that was really difficult for me and my friend. Candidate will get 4 questions to solve in 2 hr only. I was rejected in round 1 only.
The recruitment process started with an Online Assessment (OA) consisting of 4 coding questions ranging from medium to hard difficulty, with some problems being quite complex and dependent on strong DSA concepts. Candidates who cleared the OA proceeded to a Cognitive Aptitude Test (CCAT), followed by multiple interview rounds including a resume/project discussion, a DSA coding interview, and a system design/problem-solving interview. The final stage focused on communication, problem-solving ability, and overall organizational fit
Interview questions [1]
Question 1
One of the coding questions required optimizing an algorithm to handle large input sizes efficiently. The focus was on choosing the right data structure and reducing the time complexity from O(n^2) to O(n log n) or O(n).
It was quite nice actually; the interview went smoothly, the panel was friendly and supportive, the questions were relevant and engaging, and I felt confident expressing my thoughts clearly while maintaining a calm and positive mindset throughout.
I applied through college or university. I interviewed at Trilogy Innovations (New Delhi) in Mar 2026
