I have attended this recruitment via a referral. I was invited to take this test at their office in Hyderabad.
First step was to write a written test. The written test consisted of Basic Digital Design concepts, Verilog , a question from analog and a question from unix. Out of 25 questions, 10 were multiple choice questions and 15 were of descriptive nature.
After getting selected for the interview round, three rounds of interview took place. These three rounds were of technical nature. Each round lasted around 50 minutes to 1 hour. As I struggled in the interview process, the third round lasted around 25 minutes.
The interview process was about testing the basics of digital design. It was about the way in which we solve or approach the problem. They asked about concepts of multiplexer, flip flops, latches, counters , shift register to name a few. They have also asked about Verilog.
My performance was not good as I was unable to answer questions related to Verilog. They have also asked whether I took training from VLSI training institutes too.
The three rounds of interview were of technical in nature. Each round consisted of a panel of two members.
