On campus interview held at IIT Roorkee. Shortlist was based on aptitude test and resume, considering a good CGPA and all round performance. Interview consisted of two rounds, both were a mix of HR and technical, where they tested basic understanding of their business model ( which one needs to prepare beforehand) and technical knowledge of analyzing data.

Interview
Amex came to our campus for its summer internship recruitment and interview was kinda chill without any HR round. The profile was Risk & Information Management but question that were asked comprised to general analytical skills and no deep profile specific knowledge, though they asked why amex. They mostly looked for my reasoning ability in the entire process however some prior knowledge of credit cards can be beneficial if you are appearing in an interview.
