1. Online Assessment (OA)

Usually on platforms like HackerRank / Codility.

• May include MCQs on DBMS, OS, CN, and Aptitude.

1. Technical Interviews (1–2 rounds)

Conducted virtually or onsite.

Focus on data structures & algorithms, OOP, DBMS, OS, SQL, Java/C++ basics. Expect coding on a shared editor (LeetCode-style). Some teams include system design (basic for interns/freshers) and API discussions.

1. Managerial / Team Fit Round

They may ask about your projects, problem-solving approach, debugging style, teamwork, deadlines. Could include scenario-based questions like “How would you debug a performance bottleneck in production?”

1. HR Round
