Two files will be given for processing, where the raw file should be edited to the required accuracy. And once we clear those two files there will be an interview.

I was already working for Factset for a year when I responded to the interview. To external hires, this was a job opening. To me it was a promotion. The application process is how I'd put it, since it required more than just interviews. Anyway, there's a diagnostic test. Fail that and you proceed no further. So that's step 1. Step 2 is the interview with HR. You get asked general questions, the type more suited for external hires. Step 3 is the interview with your prospective supervisor. That gets challenging: what you know versus what they know, pretty much on the same work process you'll engage in. The last step is interview with senior management. I don't know if external hires go through this. I did. It was more a lecture than an interview, basically information on where I fit in the company in my new role.
