I applied through an employee referral. The process took 2 days. I interviewed at Trilogy Innovations (Bengaluru) in Dec 2017
Interview
Round 0: CV review with detailed info on projects.
Round 1: Technical round. 1 question
Round 2: Open ended problem
I applied through employee referral, so got a call for interview within 2 days. The first interview went well and Round 1 was scheduled for the next day. I got rejected after Round 1.
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 university. I interviewed at Trilogy Innovations (New Delhi) in Mar 2026
Interview
It was tough toal 7 rounds there were and the dsa is tough Trilogy interviews are very practical and performance-based, not just theory.
They usually include:
✅ Aptitude + logical reasoning
✅ Coding / problem-solving test
✅ Real-world simulation tasks
✅ Communication + decision-making scenarios
