I applied through an employee referral.

Great questions, great interviewers. The expectations can be managed in a different environment too. Rather than just going in for a 1 hours difficult short project, the candidate can rather be enquired about the process and logic one must supposed to think of.

1st Round - This was an interview round, the interviewer asked about my product understanding and my involvement with them. We had a very thorough discussion around system design and why we use what we use in our current system. He asked questions around browser calls and how a site is fetched when a link is entered in a browser. He then asked a question around DSA which basically was to limit the number of characters/numbers a variable can hold and my solution to that was to put the limit of numbers/characters in a node of a doubly linked list and then basically carry out

2nd round - They asked the infamous tail -f linux command to be implemented from scratch. It was infamous, at least for me. I started by implementing the tail command, first I implemented the class along with the method to watch live logs. I got stuck in implementing where the last 10 lines have to be printed. I assumed 40 characters per line but the interviewer suggested having a count of the number of \n. Was not able to do it then, so I started with implementing the client server websocket code and was able to run it successfully. This was the first time I was implementing it. The interviewer asked in between if I require any help. Then I tried with running the whole functionality but was unable to do so as the generator screwed it up big time. But I felt the interviewer was satisfied with my explanation as well as individually every file was working.
