I applied online and received an email from a recruiter. She asked about my availability for an interview. I responded immediately then she never wrote back. I emailed her again two days later and still no reply. I received an automated email a week later saying the position has been filled. Unprofessional and a waste of time.

There wasn't one. I was contacted by the recruiter who asked that I choose a time from his calendar invite for a phone interview. I chose a day, time and attached a copy of my resume per his request. I also confirmed via email. I canceled several appointments in anticipation of his call which never came. I reconfirmed the time zone on his email, called his office 2x and followed up with an email. It's now 24+ hrs later and no reply. And I wonder why I'm the one looking for a job?
