Slack interview questions

It was in SF, a day long. Could have done it better. Answered all the questions but I did not get the offer due to negative feedback in couple of rounds.

Spoke with a hiring manager then got a code review assignment. Took forever to get back to me and I had to message them to tell me I didn't pass. Of course, no reason given, no feedback and a complete lack of respect for my time and dignity as a person. You should be ashamed to treat people this way in the interview process
