Hackerrank screening round -
- Sliding window related question. I had already solved it in past on some platform I don't remember.
- Very simple iteration problem
Don't remember both problems but second problem was very simple, brute force worked for about 90% of test cases.
Algo/DS problem solving round -
- Previous experience discussion
- Possible to reach point A to B, if there are some walls in the matrix? Walls are sides of a cell
Machine coding round -
- Implement an in-memory queue like kafka and multiple producers/consumers on it.
Hiring Manager round -
This was the most difficult I felt and this is where I fumbled.
- Previous experience with all the design choices we as a team made and would I still make those choices if conditions would vary. Gave multiple scenarios and had discussions on them in depth. Questions on performance of tools we were using and how we can guarantee expected performance from them. This round lasted little more than 1.5 hours.
Bar Raiser round -
Again discussion on previous experience and choices. Overall work culture and what changes I could make if given a chance. And other behavioural questions.
System Design Round -
- Design a chat system with online mark and blue ticks like whatsapp. For those who don't use whatsapp - blue ticks means the message was read by reviever.
- Some questions on past experiences again.
The pattern is very much like what you would find here on leetcode experiences. Leetcode practice and friends who had applied few weeks back gave confidence.
