For Interviews, it is important for the candidate to revise his/ her academics. Basics and application-based questions are often asked. So I strongly advise that you do not neglect your studies during your graduation!
Candidates with more than a year’s work experience can expect questions around that, including about the company and the industry where they operate. For example, anyone working in a Tata company can expect to be asked about the recent boardroom battles, while those in the IT sector could be asked as to whether they feel the result of the elections in the United States could impact the IT sector.
