I had a phone round where I was asked a few Java concepts, followed by three coding exercises. The call lasted for an hour, and the interviewer was nice to speak to.

I later had an onsite interview with six rounds, of which three were system design and two were coding questions. The process is exhausting, as it takes seven hours at a stretch, including the lunch round.

Most of the engineers were nice to speak to, except for a couple of them. One Senior Engineer who asked me a system design question had a set answer in his mind and wanted me to arrive at it, which I found annoying, even though my approach was as good as his, which he eventually agreed to.

One of the coding rounds was with a junior engineer, and he lacked experience, which was clearly visible because he wasn't able to follow my code. His instructions were also contrasting from the beginning of the interview to the end.

The coding round was to implement a HashMap with primitives and find all palindromic subsequences. System design rounds were specific to LinkedIn.
