Standard.

Recruiter -> Hiring Manager (she was awesome) -> Technical. Didn’t make it to the final round.

I crushed the technical so much that I had to teach my interviewer how some edge cases in their question could break given some input. I also had to explain how programming works. They led me in the wrong direction multiple times, but I was able to finish the algo within 30 minutes.

I got rejected and asked for feedback. They said I didn’t know Python and that I needed too much assistance during the technical.

I think they confused me with their developer who interviewed me.
