I applied online and HR contacted me in after a week for a telephonice interview. in 2 weeks I got another email from HR to come for an in person intrview.

There is phone interview first, manager of the QA team called. after this they offered the date and time for in person interview. In-person interview includes a test (on computer) and 2 plus team members will interview, if someone clears this phase will be called for another interview with 2-3 management personnel (Software, HR, Technical Support), if candidate clears this stage and they like him/her, is offered the job.
