1. Online Assessment (OA)
Usually conducted on platforms like Codility, HackerRank, or AMCAT.
Duration: 90–120 minutes.
Format:
2–3 coding problems (DSA-focused).
Difficulty: Easy to Medium-Hard.
Topics: Arrays, Strings, Trees, Dynamic Programming, Graphs, Hashing, Sliding Window.
Sometimes includes MCQs on CS fundamentals (OS, DBMS, CN).
Tip: Practice on LeetCode (Medium), especially Microsoft-tagged problems.
✅ 2. Technical Interviews (2–3 Rounds)
Each round is 45–60 mins.
Focus:
Data Structures & Algorithms (most important).
Problem-solving approach (not just the code, but how you think).
Complexity analysis (Time & Space).
Core CS concepts: OOP, DBMS, OS, Computer Networks.
Coding language flexibility (Java, C++, Python preferred).
Sample Questions:
Design an LRU cache.
Implement autocomplete suggestions.
Merge K sorted lists.
Find shortest path (Graph problem).
Expect follow-ups like:
“What if input size is 10^7?”
“Can you optimize further?”
“Write test cases.”
