You first need to submit your CV on their website and I was contacted by a recruiter two weeks later. The process is pretty similar to what they describe online: Interview with HR, meeting with the hiring manager, Pleo challenge, and team meeting (I didn't get that far). They were pretty realistic with the challenge and it was crafted to the role I was applying for. Got 4 days to get my answers back and it does take some time to have them ready (they were all open-ended questions). I got very detailed feedback explaining why they decided to move forward with another candidate, which was a nice refresher from all the other hiring experiences I have had before.
