It was a great experience. The HR got sacked while he was taking my interview, and it was fun to see him disconnect before my interview was over. I got the job, though.

Multiple rounds of LeetCode-type questions. Their level was between medium and hard, and in many cases allowed for many different solutions and improvements. The whole interview was code-agnostic, and nobody cared for typos.

I solved all of the problems in a quick, efficient manner, far sooner than the time was slated for. I didn't get a follow-up. Not sure what happened, but there should have been a follow-up.
