It was a four-round, 45-minute technical interview. You can schedule the rounds the way you want. I decided to have them all in one day to get it over with.

Standard technical questions were asked. I would say all of them were medium-level. LeetCode (LC) isn't enough for prep, though. The questions give you limited information, unlike LC questions where you get mostly everything upfront. You have to ask clarifying questions before answering to avoid losing time.

I unfortunately did not prepare for this style of technical interviewing before, but if anyone practices this style, everyone has a good chance to pass.

Insertion sort was one of them. I don’t remember the rest.
