Interview Day:

• 1 round of problem-solving
• 1 round of behavioral
• 2 rounds of system design

I performed very well on all rounds except the first design round. They wanted to redo a design round, and I asked them to review the second design round, as I did so well on it. They stated that was a calibration round and I wasn't in the random set of candidates for which they'd use that round. So, basically, an hour of my life was wasted, lol.

It was frustrating, but I did a third design round on short notice as I had travel plans for a whole month ahead. Unfortunately, I didn't make it.

I'd say everything else about the process was smooth, and the recruiters were extremely helpful.

For problem-solving, I remember questions I'd categorize as LeetCode mediums.

For system design, I was asked:

• Design a trending topic engine for a social network.
• Design Messenger.
• Design a LeetCode/CodeForces-like system.
