Capgemini Software Engineer interview questions

2 rounds 1st was intense MCQs based on OOPs and Math + 4 Coding questions. 2nd Round is a Skype interview includes building a prototype for the given case study. I was pretty confident after the 2nd round and was so sure of getting an offer. I followed up with HR who is from new york , after month of follow up and few messages over linkedin he responded saying they are having issues in OPT approval process. I tried to follow up on that issue as well hoping that it was not a rejection for me. Finally after so many messages HR responded that the team for which I interviewed has stopped hiring people and the other team is not willing to move forward, I am not sure what went wrong in this process.

First round was telephonic and asked questions on my experience and areas of expertise. Next round was face to face and third was HR round. In second round more technical questions were asked
