Recruiter was 7 minutes late for the phone screening. (1st red flag) During the course of the conversation, the recruiter sounded very unengaged and unenthusiastic throughout the entire time. At one point, there was a long 3-4 second pause after I answered one of the questions which I proceeded to ask if I may ask questions about the company itself. (2nd red flag) Overall, the interview cut short 16 min of the total expected time after I had asked everything I could do to prepare. (3rd red flag) I knew right away I was not going to proceed since it seemed that they already had a list of candidates to go through to the next round. If that is truly the case, it is very unprofessional to give me a pity call and not respect my time that I prepared. Easily, they could have told me prior to my schedule that they've already moved on and it wouldn't have been a problem. A true blessing in disguise I didn't get through if this type of unprofessionalism is part of the company culture.
