Interviewers are very intimidating most of the time; but if you're lucky you'll get a really friendly one who asks all the right questions. Some of the people who were interviewing with me complained that the questions being asked were irrelevant to the job position they were hiring; they seemed to be following the trend that Google set, asking software engineering questions for technical support positions, which seemed out of context.

Basic typing, analytical, and English language assessments at first. It was followed by an initial interview by the HR. Then by a Mock call. Lastly, final interview by one of the Team Leads. After you passed, you will be given the Job Offer.
