Came on campus.

OA + 4 rounds.

OA was simple: 2 easy DSA questions. I finished the test in 9 minutes.

Interview:

Round 1: Good interviewer, polite.

Puzzle: Some coins are given, 11 or 14, I don't remember exactly. One was heavier and two were lighter. Find all 3 types of coins in minimum comparisons.

Java-based OOPs, HashSet vs. HashMap, SQL query with GROUP BY, projects, DBMS referential integrity, merge sort basics.

Round 2: What is inheritance? Explain with an example.

DSA: Reverse level order traversal on a binary tree.

8-piece cake puzzle, 2-candle puzzle, another heavy coin puzzle.

Implement a queue with stacks.

Round 3: HR Why SAP? Want to do MS? What if you don't like your project?

Round 4: HR Tell me about yourself (non-tech stuff). Discussion about one of my hobbies for 15 minutes and family background.

Oops, and Java-based questions.
