There were 3 steps of interview process:
1. Phone HR interview
2. Phone technical interview
3. 1 to 1 interview with company's guys
Technical interview was related to my previous experience and testing of my technical back ground.
1 to 1 was just testing of my English spiking skills and personality testing, T think.
After step 3 I got the job offer in several days.
