Friendly interviewer, most about projects in statistics and asked some statistics basic concepts. I waited for a long time (almost 2 months) until the next step, which was a rejection.

Interviewers were kind and patient. It was a 45min test "interview" online. Evaluated probability, math, statistics, finance and programming. I wasn't given any info about the content of the evaluation I supposed because this are things you just don't learn for the interview. My advice to you: be aware of your limitations but also acknowledge that this tests are not a reflect of your capabilities. Not knowing how many zeros are there in 20! (factorial) is not an indication that you'll suck in this job. Personally I was roasted in this evaluation but I think I'll be ok. I hope this won't happen to you too. So, here are the test questions.
