An online test was conducted, consisting of three sections:

• Quant
• Basic C
• Electronics/Software/Communications

I chose to give the exam on Communications and was shortlisted for interviews.

Three rounds of interviews were conducted. The first one was based on my CV. The interviewer asked some puzzles and some questions on algorithms. The second round was more technical, and I was asked questions on linked lists and bit operators. As my CV has more projects related to Communications, he asked me questions on the basics of digital communication and wireless communication. The third round was with HR, and she asked me about my extracurricular activities and my contribution to the projects I worked on.

The interview was a pleasant experience, and Qualcomm was my dream company. The interviewers were very friendly and offered some hints when I was stuck. You need to be prepared to explain each and every term in your CV and also have knowledge of basic C, OS, and data structures.

All the best!

Basics of MIMO, OFDM.

I was asked to design a circuit to control a motor so that a water tank is never full nor empty.

Another question was to write a code to change 0xEF into 0xFE, which is a nibble swap. The interviewer gave me a little help with this.
