I got a job through a Who’s Hiring post that helped me move to Copenhagen, DK. I’ve gotten a few interviews through Who Wants To Be Hired, mostly interesting companies who then ask me to apply as if I was a regular candidate.
In one case, I got a very nice email from the CEO, I applied, but I was never told what kind of position I was interviewing for, so it was really tough to tailor my answers and focus.
