I sent my CV and didn't get an answer from JetBrains. So far, so good.

I eventually switched jobs and moved to a new country. I then out of the blue got a half-baked e-mail with some silly story on how they "lost my original e-mail in the system" (if so, how did they "find it", now?) and if I was still willing to relocate from my original country to Germany. So it seems that taking 5 seconds to look at the LinkedIn profile that was provided both in the original application e-mail and CV would be too troublesome to the clueless recruiter that handled this application.

They asked me if I was willing to move from a country in which I wasn't even residing.
