Standard Chartered Bank Summer/International Graduate Program interview questions

The process for the internship began with online test then included two interviews; one by phone with HR and another with user. The interview with the HR took approx. 1 hour; they asked a lot of details and some random questions such as : what's your favorite color? what's your fav food? Then the user interview was very chill; but all depended on who was interviewing. After I got the internship, I was offered an interview with a division head. It was very brief; about only 15 minutes. The question was very simple : tell me the biggest challenge you've ever faced. About two weeks after the interview, I got the offer for the IG Program.
