I remember a recruiter reaching out to me after I applied to a company and we set up a phone interview. When the date arrived, she did not call. I emailed her a few days later and she did not reply. A few weeks later she contacted me again, and since I hadn't secured a job yet, I decided to give it another shot and we set up another phone interview. Guess what? She didn't call. Second strike was too much for me, so when she emailed about a couple of weeks later to know if I was still interested, I did not even bother to reply.
