The process is not too long, first you do some test on their website, then you have a call with HR and after that the technical interview (90 minutes). During the technical interview you have to explain a lot of concepts, do some practical exercises and write SQL queries. I didn't pass the tech interview, but the HR girl was nice and willing to answer any questions I had about it, so I asked for feedback and I don't know how to take it but this is what I got: “I would suggest reading the book "CLR via C#" book by Jeffery Richter. It will explain the core concepts of the C# language.” -- Hope my contribution helps! Good luck!

It was a two step proccess, common questions regarding programming etc. At the end I got a positive feedback and overall everything was very okay. I have a very positive feelings.
