The interview process is quite different from most other companies as they may ask you personal question such as what is your working lifestyle, your hobbies and many more. There will be not that difficult question as mostly you will able to answer them. There is some technical question in between the interview but they are not that hard to answer unless you don't know or you didn't learn that.
