The interview process consisted of 4 steps: 1. The first interviewer was very nice and friendly, it was mainly to get to know my background and experience. I also got the feeling that she was checking my english (my second language) and conversational skills; she asked me stuff like "why do I want to join totpal". She also explained how toptal works and provided me with tools to study for the next online coding test in Codility. I encourage you to do first the demo test and check hackerrank too to prepare. 2. Codility test: this was the most difficult part for me: it consisted of three coding challenges, one of them was not easy but not as hard os the other two. I just completed two challenges, with one at 1005 and the other one at 70%, since my solution didn't passed all the tests. 3. Screening test: After I finished my codility test, I received an email asking me to schedule an interview with a toptaler. This interviewer asked me to share my screen and open whatever environment I felt more comfortable with, so I used xcode and swift. The two questions were very easy; I solved the first problem in 5 minutes but got stuck for 10 minutes in the second one, but managed to solve it on time. About the interviewer: he didn't seem very friendly or helpful like other interviewers.
