1. Online OA with CoderSignal to start with. It was very standard and not hard.

2. I got through to the four interview rounds, which can always be divided into two parts of two interviews each.

• The first part consisted of two CoderSignal assessments of medium difficulty, both of which I managed to complete.
• The second part included a system design interview, which I found to be average, and the interviewer was also okay.
• The behavioral round was standard.

No wonder I didn't manage to get the offer.
