First they arranged a short interview where they described me the process. After that I had a longer interview in which they asked me about my experience and techs I had worked with. Afterwards they sent me a 60 minutes Hackerank quiz. The next step was a programming challenge which I had to turn-in in 5 days. After the challenged they gave me a pre-offer but it would not be effective until a client hired me. Finally I had a interview with one of their clients and then I finally received my offer. The process took a bit too long but overall I think it was a positive experience.

The process was amazing! The tests that are applied are completely related to the programming task you're applying too, so that's a plus. My recruiter was really gentle and I felt comfortable in the entire process.
