Q1- Merge overlapping intervals. I was able to solve it in O(nlogn) time, and constant space complexity. Q2- Given a transactions table, containing following columns: id, amount, from_acc, to_acc, created_ts, last_updated_ts. Create EOD balance view: account_id, date, eod_balance I didn't remember exact syntax for writing the query, so I told him my approach, and I told him I'll need to google exact syntax. 3. Clone a graph. I discussed the approach, and interviewer told me idea is correct, and/ to go ahead with my implementation. But I did dfs instead of bfs for cloning. And interviewer didn't give me any hints. Time ran out so I wasn't able to test out this solution. If interviewer hadn't wasted 10 mins at the start of interview, or compensated for wasted time, I would have corrected this solution

(Final round interview) Write a Python function that computes the check sum of a file. Then, modify the function such that we compute the check sum of a file every k bytes. I was allowed to refer to documentation for this exercise
