I applied online, and the process took 2 days. I was interviewed for the position of Senior Software Engineer.

Process was very fast. I got a call, and the interview was arranged. There were two F2F tech rounds and one HR discussion with the HR-VP, followed by a salary discussion with HR. Both tech rounds had very low-level questions, as if they needed to hire someone for the position. If you are from a premier institute, you are already 60% qualified.

There were two rounds:

• In the first, they asked very basic questions about Java core without any tricky questions, which included OOPs fundamentals, ArrayList, and LinkedList. A few basic puzzles were also asked.
• In the second round, I was asked to design an ATM machine and provide all the functionality, describing the methods, its structure, and designing. If you know the basics, it's quite simple.

Finally, there was a VP discussion, which was just a formality where I was asked about my future goals and the improvements and ideas I could provide within the organization. Then there was the final salary discussion. HR had already decided the salary that he wanted to offer, stating the fixed structure, which I accepted, but I should have negotiated.

Design the implementation of an ATM machine.
