I applied online. The process took 1 day. I interviewed at Ampfield (Stockholm, Stockholm) in Jul 2015
Interview
The interview starts with a rather challenging IQ test, you have half an hour to answer 20 questions.
Then comes a web based personality test, and a short discussion on the results.
The third one is a mathematics test. You have indefinite time to solve as much as you can from a list of problems.

Why do you want to work here?
What other jobs are you interested in?
Do you feel that the personality test result fits you?
I applied online. The process took 1 day. I interviewed at Ampfield (Stockholm, Stockholm) in Aug 2016
Interview
The day starts with an IQ-test of average difficulty. Then comes two personality tests from free websites. Then a lunch with the CEO and then a really hard mathematics test. There was no real interview part. The lunch was the only part where you actually talked to someone but it was only about physics and nothing about the job or about me. If you have a masters in engineering physics like me, it is a waste of time to repeat mathematical courses as the questions were about concepts way above the courses I have taken. Things like Wiener processes (a lot of them), hyperspheres/cubes and the like.
Overall it seemed like more of a chance for the CEO to show how smart he is as opposed to being a normal job interview.
