A very complicated, timed, bit transformation question.
Experience of data engineering and platforms
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
(Online assessment) Write a Dockerfile to containerize some application by some criteria (must be Ubuntu, move directories, etc)
(Final round interview) No coding here, just overview of my projects as well as typical behavioral questions (how do you operate with concurrent tasks, how do you get up to speed with the team, etc)
(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
