Round 3

TECHNICAL AND HR

Interview Experience
Icebreaker question- Tell me about yourself.
1. A question on tree Data structure.
2. I was asked about my Project work in college which was on Operating System. Detailed explanation why and how I picked this project. Who were the group members, how was the group formed, how much was the involvement of college faculty? What is its use in future? What was my role in the project?
The interviewer pointed out some flaw in algorithms used in project. Basically he asked me to think of Data Structures through which insertion can be done in O(1) as well as deletion and retrieval in O(1)…like the implementation of LRU cache algorithm.
The process took 40 minutes.
3. Discussion on second project which was on knn algorithm.
4. Asked me about tiny Url or Url shortener. Implement it.
Interview Tips
The interviews were really thought provoking and the interviewers were helpful and friendly. It felt like solving problems as a team and not at all like a test. The interviewers were quite receptive to our questions and patient.
