Broadcom visited our campus on August 13, 2011. They offered two job profiles: a software profile and a hardware profile. They had separate tests for both profiles, but the tests were conducted simultaneously.

The test for the hardware profile mainly consisted of questions on digital electronics and the basics of analog and digital communication. For the software profile, the paper included questions on probability, some mathematical puzzles, and C programming. The paper was subjective for the software profile, with simple C programs asked. The paper for the hardware profile was objective.

The next day, candidates were shortlisted for interviews based on their test scores.

They had two rounds of technical interviews, and the questions were mostly concentrated on the fundamentals of wireless communication, coding theory, and OFDM. I was asked about the projects I had mentioned in my CV. The final round was the HR round, which was a mere formality. They finally selected seven people from our college, and it was a good experience overall.

How is orthogonality achieved in OFDM?

Do carriers maintain orthogonality after transmission?

What is a MIMO system?

Are sin(t) and sin(t+theta) always orthogonal?
