I was contacted by a "Lead Senior" Recruiter from GM via LinkedIn 6 months ago.

I spoke to the recruiter on the phone about the role, and he/she said she was going to pass the information to the hiring manager and schedule a video interview.

In the process, I did not hear from the recruiter for a few weeks. Finally, she/he got back to me and said that the conveyor engineer position was put on hold, but if I was interested in the "plant resident engineer" position, I could interview for that.

So, I did a video interview for that position.

I heard nothing for 2 weeks, so I emailed and was told that I was still up for consideration and that the recruiter would let me know as soon as the HM made a decision.

I heard nothing for 5 weeks after that. Then I got an email from the same recruiter telling me that the conveyor engineer position was open again, and the HM would like to interview me.

I said sure, but what happened to the other position. The recruiter's answer was "it has been filled."

Finally, I was getting to schedule the interview when I received and accepted another offer. I respectfully declined the interview invitation and said thanks for the opportunity, and got no response.

Really unprofessional way of doing business with prospective employees.
