Coding problem1

It was in the evening. I went to their office in Gurgaon. It was taken by one of the technology director who had a lot of experience. 
 

1. I was asked questions related to how credit card business works which was related to working of company.
Problem approach
  • This was basically a company-related question and maybe they wanted to check if I've studied about the company. It was more of a conversational round and I answered the questions pretty confidently. And finally got the offer after this round.
