problem was easy, then medium follow up. was able to solve first part but needed hints to optimize. interviewer looked like he did not want to be there. Was a little rude and didn't make me feel welcome.
Codesignal consisted of 4 questions, followed by a live coding interview. Interviewer wanted the optimal solution to a hard problem, and was quite confusing in what they were asking for.
one phone screening, and then virtual onsite, including 2 coding rounds, one system design and one BQ. For the coding rounds, they are hard level. For BQ round, I was asked previous project and explained it end to end.
