The interview process consisted of two rounds:

1st Round: This was an intense MCQ-based round covering OOPs and Math, followed by four coding questions.

2nd Round: This was a Skype interview that involved building a prototype for a given case study.

I felt confident after the second round and was sure I would receive an offer. I followed up with the HR representative from New York. After a month of follow-ups and several messages on LinkedIn, they responded, stating they were experiencing issues with the OPT approval process. I tried to follow up on this issue, hoping it wasn't a rejection for me. Finally, after many messages, the HR representative responded that the team I interviewed with had stopped hiring, and the other team was not willing to move forward. I am unsure what went wrong in this process.
