The agent that called to schedule an interview was very unprofessional, I sent him an email (that he gave me) with my availability for an interview, he called me on a Sunday, while I was at work at 6pm, to do the interview when it was outside of my availability and told me "I don't check my emails". He then never sent me an email to confirm the time for the interview, he forgot to call me the day of the interview, I emailed him to let him know I waited all day for his call and ask him if we could please schedule a proper time and date again, to subsequently get an email 1hr after with a subject line that read "FINAL ATEMPT TO CONTACT YOU", did not acknowledge the email I sent him (maybe because he doesn't read his emails), he said he tried calling me and I never answered (I had a phone interview with another employer that day and my phone worked just fine), he then, in a kind of threatening way wrote this is the last time I try to contact you. I replied telling him I was no longer interested because of the unprofessionalism and because my time is valuable.
