1. Online coding round

1. Platform was codejudge, total question - 4, time given - 90 minutes.
2. 1 easy(bit manipulation), 2 medium(greedy and recursion), 1 hard (graph).
3. I had solved first three problems completely and last problem paritially(5/10) .

2. Technical Interview-1

1. Find longest consecutive one's in a binary string. [ EASY ]
2. Find the maximum rectangle area in sorted binary matrix.(in O(m+n) complexity) [ MEDIUM ]
3. Count number of Islands with some variations [ EASY ]
4. Josephus problem ( only approach )
5. Then asked some questions on DBMS(index, ACID property), critical section and some discussion on project and my resume.

3. Technical Interview-2

1. Started the interview with some behavioural questions.
2. Min stack problem (proof + code) [ MEDIUM ]
3. DP problem . Given an array of piles ,you had to make two pillars of same length by using those piles. That length should be maximum as much as possible. First I solved with it recursion and then use memoization. [ MEDIUM ]
4. Tarjan's Algorithm (only approach)
5. Then some questions on OOPS, DBMS,OS.

4. CTO Round

1. General discussion on projects, company work, on my skill sets.
2. It was only for 10 minutes.
