Interview Preparation Tips
Round: Test
Experience: Each section had 20 multiple choice questions and each section was allotted 30 minutes. The aptitude section was fairly difficult due to time constraints. The other two sections had several questions with unfamiliar concepts; however the other questions were easy.
Tips: Practice aptitude questions to increase speed in problem-solving.
Duration: 1 hour 30 minutes
Total Questions: 60
Round: Technical Interview
Experience: The first round was fairly short. The interviewer asked only three questions and I was able to answer all except for the overlap-add question. However I had the intuition to get to part of the answer.
Tips: Just brush up concepts in analog communications and DSP.
Round: Technical Interview
Experience: The second round was longer. The interviewer asked questions mostly in DSP and analog communications. I was able to answer all but one, which involved interpolation in discrete-time domain. The interviewer gave hints on how to get to the solution of the bit-rate and the interpolation question but I was able to answer only the former. The interviewer also asked if I did a course on Linear Algebra, and I affirmed it but I had no memory of it.
Tips: Just like in the first round, but expect more difficult questions.
Round: HR Interview
Experience: The HR interview was very short and the interviewer did not ask any of the typical HR questions except for if I were offered an internship in Communications, I would take it.
Tips: If you make it this far, you'll most likely make it. There is no need to prepare anything in advance.
