Probably the worst interview I ever had. First you get in touch with a recruiter, following by a tech screen interview with one engineer with commons questions that I don't consider difficult. Then you have a home test to do which follows a meeting to discuss your solution with two engineers. One of the interviewers was all the time writing on slack/chat/whatever meanwhile I was trying to think a solution. I didn't have "context" about what to expect in this meeting, in the test said no third parties/techs allowed, so I took my time to review pure code concepts/algorithms. But then they started to ask about libraries/third parties implementations, I've worked with many of these techs but I didn't consider that was necessary to review them since third parties were not allowed in the test. Candidates have the right to know what to expect and prepare accordingly the interview.
