Zookr SDE Interview Experience

I had a chance to interview with Zookr.in through Linkedin by contacting their HR. First, they shared a problem statement along the lines of competitive programming and gave me two days to come up with all kinds of possible solutions along with a report on the best possible edge-case solution.

Post the submission of the problem, they found a lot of errors in my edge case cut but they liked my approach and called me up for the F2F interview.

F2F round 1:

1. My college projects in detail. (Here I was on the losing end)
2. Smallest subarray with sum greater than or equal to a given value. (I got stuck in this)
3. Discussion on fork() method & threads.
4. Discussion on MySQL and joins

F2F round 2:

• Difference between http and https. Some discussion about web servers
• Asynchronous Task Queuing in detail (Third world problem for me 🙁 )
• Puzzle – One bulb, 3 switches, minimum attempts to know the bulb’s switch.
• N Queen Problem. Details understanding of Backtracking. I was not selected but I enjoyed the interview experience with the Zookr.in Team. They predominantly focus on data structures and algorithms.
