I applied through college placement drive. There was an aptitude test first. Which included a communication part: "Write about how you would adjust to life in a new city if you got selected by Thorogood". The second part was quantitative analysis and data interpretation questions. After aptitude test, there was a round of interview. It was mostly about my projects mentioned in CV. Then next round was Assessment Centre, which is a day long process with 4 parts: Case Study, Fact Finding Round, Group Discussion, HR Interview. This part doesn't really need preparation. You just need to be good at solving problems on the spot.
