They asked me questions on oops, java fundamentals and one DSA question of reversing an array. Questions were asked related to my projects, since I had used API calling, questions revolved around using API. Then some general questions like why idfc, are you open to relocation were also asked.

It was simple, just a screening followed by 2 zoom interviews. I had to prepare with some STAR questions and an elevator pitch. The interviewers were pretty nice overall, and my 2nd round interview felt more of a conversation.

Cold applied, couple of days later received a first round, a 10-15 minute call discussing more about yourself and whether you qualify for the opportunities, after that they immediately tell you whether you move on to the final round or not. The format was back to back 30 min interview later that week, mostly behavioral with few questions about your classroom learnings and skills using computer.
