I have been contacted by a recruiter, which seemed to be from a 3rd party company, in regards to my availability for a PM II role, for which I applied to 2 months back. The lady was very agitated and grave, underlying de urgency to fill in this role as quickly as possible. She connected me with the hiring manager via email on Thursday, so that we can schedule a screening interview. And that was that. He didn't reply to my emails, he just sent a blunt invitation to interview almost a week later, on a Wednesday to invite me for a discussion in less than 24 hours - Thursday. I politely declined and rescheduled for next week, agreeing to a convenient hour for both of us on the coming Monday. During the weekend, I receive another invitation, with an updated timeslot. I have asked if this was intentional, or by mistake, but no response from the hiring manager. In the end, we had our discussion on Monday, and by Thursday I receive an email from Microsoft Global Talent Acquisition that the qualification requirements for the role have drastically changed and I am invited to re-apply. What can I say...I was not expecting this level of unprofessionalism.
