Broadcom interview questions

I applied on line for this position. Few days, I received a call from the hiring manager (during the day) asking a some technical questions. I manage to clear this unscheduled phone interview (This was highly unusual since I was never notified) and was received a request for an in-person interview. From the beginning, this was very disorganized. I was interviewed with eight different and got rejected few days later.

Received phone interview. One people. Ask technical questions about OFDM system and past experience on resume.
