Beceem Communications Design Engineer Interview Questions and Answers

Round: Test
Experience: There were some basic questions on probability theory, digital communication (mainly wireless communication, like problem on GSM, CDMA, and OFDM). Some questions were from DSP (like DFT etc.). Basics of information theory (EE 624) should be clear; there were some questions on calculating capacity of a Gaussian channel, differential entropy etc. A single problem from C programming was there and it was very simple.
Two sections : 1) VLSI 2) Communications

For VLSI stream we had to solve only the first section.

Type of questions and details :
Questions were a mix of digital and analog.
Most of the questions were on digital logic design.
1) Given a current mirror circuit we had to identify and calculate what is the current through one MOS Transistor.
2) Question on timing analysis-setup time, hold time ----this very important---you have to be very clear in this concept. Frequently asked.
3) Question on Op Amp. It was an integrator …had to calculate output voltage.
4) Many questions were on logic design.
5) Questions on devices like if doping increased, how would the other parameters vary..?
Duration: 60 minutes
Total Questions: 30

Round: Technical Interview
Experience: View 1: He asked me most of the questions on my thesis and my previous projects and term papers (related to wireless communication). I was also asked about viterbi decoders, OFDM and MIMO (my thesis was on MIMO).
View 2: Questions were mostly on timing analysis.

General Tips: One should try to keep himself focused during the whole time of written test and interview. Basics of probability theory and communication theory should be very clear.
Skill Tips: Be well prepared with both digital and analog. You must know Verilog.
Skills: Probability, Coding, Information Theory, Wireless communication
