I interviewed with a VERY large company that's a household name in the semiconductor industry.
The hiring manager and a programmer reached out to at least 2 of my current colleagues immediately after I left the building.
I was blasted the very next day at work. The whole damn building knew I interviewed with this “fantastic organization.”
Kicker:
I omitted my current employer from my resume and just listed my title, job duties, and tenure.
It was brought up in the interview and told them explicitly that I didn't want to divulge this info.
They were adamant that I disclose. So I did.
Now, I'm fucked.
