It was a very pleasant experience. At first there are two test - one is math&logic test the other one is personality test. Then there was an interview with HR and Team Leader. It was quite nice and I liked both of them. Quetions were clasical, you can prepare for this inteview by reading the first website on topic of "most common inteview quetions", but most qetions dont really need any preparation, you can just answer how you feel it.
