I applied through a recruiter. The process took 3 months. I interviewed at ESTEC
Interview
The interview process was long, standard interview questions, two interviews. I believe the second interview was useless, seemed repetitive. The atmosphere was relaxed and friendly, my first interview didn't go to well and I wasn't expecting a second call, but I did. Second interview went great, even talked quite a while about when I can start, got my hopes up, but didn't get an offer. Nonetheless, it was a good experience. Very competitive to get into ESA.
