Someone wrote to me on linkedin for a php job. I had enough time and accepted the interview. We set it for the next day at a time that both me and the recruiter wanted.
I waited for him to even contact me until 5-6 hrs after the time we set, to tell me he was busy with meetings (wtf you wanted 14pm). I gave another chance and we set the interview the next day at the same time.

I waited for 2-3 hrs. This time he wrote me back even later, it was almost midnight to tell me the same excuse.

Is this a red flag for you? Should I even consider working with this guy?
