Had a great 1:1 with recruiter and then was set up to meet with hiring manager. As most interviewees do is to prep extensively for second round interviews. Much to my surprise the hiring manager started off with asking me if I had any questions and I proceeded to go down my list. I then asked what questions they had for me and the had none. At this point I knew that this was a bogus interview with no direction and that this person had wasted both of our time. I did the polite thing and continued to ask more questions when I should have just have called it a day! Very disrespectful to even lead a candidate down a dead end road. I was then told by the recruiter that my background didn’t meet the criteria. How would the hiring manager even know as they didn’t asked me one question! I wish companies like Slack would not waste our valuable time.
