Had 1 technical interview followed by 2 technical interviews at their location. I enjoyed talking to the first 2 engineers but the last was unbelievably awful and was trying to make me fail.

He asked me such a difficult problem and purposely gave me some wrong info to see if I would catch it or not, changed the scenario while I was near done solving it, and clearly told me he'll notify the other interviewers that I did so poorly. I spoke to everyone else that interviewed with the company and they only had 1 or 2 technical interviews with simple problems.

They were completely shocked at how I was treated by the last person. I'll make sure to never apply to this place ever again.

The topic was a dynamic algorithm design question.
