three rounds of interview, 1st aptitude test, which test your logic,maths and language (written), 2nd HR round which was more about career aspirations, future goals, and 3rd was technical round which was more about market research. Though 3rd round was about MR and if you don't know much about it...then also its fine. Only think you need to do is don't bluff, just be frank and say you don't know...and i am sure u will still be hired because of your truth. Level of difficulty was medium. Tip: Dress-up professionally and neatly.
