Worst recruiter experience:
Recruiter sets up interview with a company. I get to their office - the most packed place I have ever seen - devs practically sitting on each other, and the QA guys are being used as chairs....

So I wait for 15 minutes near the doot till the interviewer gets to me through the incredibley noisy openspace, and shakes hands. We go into a mess of a meeting room - and he explains that they will be moving to a bigger office soon. I say - looks like you should have moved by now....

Anyways - he askes me to tell him about myself - and I explain my background, Focusing on Android dev experience - The recruiter told me this was a senior Android dev position. The interviewer has a huge question mark above his head, but waits for me to finish. Then he tells me: so... no backend experience? so Now I have a huge question mark above my head...

turns out he is looking for BackEnd devs - Not android devs.
