Very unprofessional. I initially applied for a consulting internship position and got a Hirevue. Didn't hear anything for a while, so I just assumed I didn't get the position.
I got an email from a totally separate recruiter 2 months later that said they stumbled across the info I submitted for the previous interview and asked if I'd be interested in a different position. I said sure. Recruiter said I didn't have to take any further action, and that she was still in the process of considering applicants, so she'd let me know if we could move forward. A few weeks later, I get an automated rejection email.
Umm, why individually reach out to someone asking if they'd be interested in a position, only to not interview them at all and then auto reject them? That's pretty slimy in my book. Maybe it’s a good thing they never followed through- I don’t know if I’d enjoy working for a company that treats its applicants with such disrespect.
