Interviewed, starting with a single technical interview (which I think was a screening round).

Only did okay in that round, so I think they just used that interview as a first-pass filter.

After that, four interviews were scheduled all at once and all in the same day: three technical and one hiring manager.

The interviewers were all very nice, and they each had a different kind of technical question.

The hiring manager interview was mostly standard "what's a challenge you've faced" type questions, along with a very easy technical portion.

What was a time you made a significant mistake?

Coding questions were Leetcode medium, one string-based, one DFS-based, and one tree-based.
