The interview process is hard to get in the first place and is even harder to pass once obtained. You can usually get an interview by receiving a referral; apart from that, it's difficult.

5 rounds: 1 behavioral and 4 technical. Overall, not very hard, but I could not get the optimal solution in the first technical round. I also spent too much time explaining my solution in the third technical round.

Not bad; it was very technical, but the people were nice. I think I learned a lot from the experience and am thankful for the opportunity to have interviewed here. As I am new to the field, this was good for familiarity.
