I had a very unprofessional experience with a recruiter. A recruiter reached out to me about a role that he thought I'd be a good fit for. We scheduled a day and time for a phone call. I waited about 10 mins and nothing came. Then I got a message from him saying he tried calling but received a busy signal. He asked that I schedule another day and time. I replied back right away and asked for his phone number. He didn't reply. So I sent a second message with another day and time. That day and time came and he never replied to it and he didn't call either.
