I applied online and was offered an interview within a few days. We had set it up for a Friday morning at 8 am, I woke up to an email from the recruiter saying she had meetings to plan for and asking if I could reschedule. I said yes and gave her my dates that would work for the following week. I heard nothing back from her that entire week. I sent a follow-up email to her the week after letting her know i was still interested and willing to interview, when again I got no response. Poor professionalism. As a human being I felt that even if the position had been filled, I was offered to interview, she had to reschedule, and I at least deserved a response.
