I applied through Dell Careers. After two or three weeks, I received a call from a recruiter regarding an interview.

I attended the interview process, which included the following rounds:

• First round: A C programming test, which included predicting output and some simple programs.
• Second round: A technical round, with questions primarily from C, microprocessor, and OS.
• Third round: A managerial round.
• Fourth round: An HR round.

The next day, I received a positive response.
