I submit my resume online the call me first for a interview schedule, after a week the take my interview. Interview was very much with all technical question. They want to know full details about my past job experience and my depth of knowledge. My interview was for 30 min duration. After 2 weeks they confirm me for this position.

Not very difficult. They're more interested in your personality to ensure you're a good fit with others. It took about a total of two weeks. Phone interview followed by 2 in person interviews. They interviewers were very nice.
