Took like 4 weeks until I reached the final interview. Once I've sent my application, I've got an invitation for a one-way interview, then took like 10 days to receive an email saying that I passed and got an invitation for the initial interview. They were interviewing 100's of applicants within the day, so make sure to adhere to your schedule or at least be there 15 minutes before. They just asked more about your previous employment and made sure that you have your equipment ready and that you are not currently employed by any employer. Passed the initial interview and got an invitation for the final just a day after. Repeated some questions that were already asked during the initial which I think, kinda unnecessary. Did a mock call with a script provided by the TA hours before the actual interview. I didn't pass it, but they did not provide individual feedback as to why. It was just a lame excuse saying that they don't have time as they are attending to hundreds of applicants each day. lol.
