4 Interview Rounds
Interview Preparation Tips
Round: Test
Experience: Aptitude section won't be a problem.Questions were simple and straight forward.
Decent knowledge of C and C++ will be enough to answer the Programming section.
I chose communication in the 3rd section.I was expecting questions related to signal processing.But most of the questions were related to communication like modulation, quantization level, Shanon's therom etc.The course wasn't done yet for us.So I was able to answer only 5-6 questions and the remaining I took some calculated guesses to the best of my knowledge
Tips: Select communication profile only if you had done a proper communication course.Signals and Systems & Digital Signal Processing courses won't be enough.While preparing concentrate on one area and prepare well.It will be useful for both exam as well as the interview.While answering the 1st two sections of the test time management is important as the questions are easy and given the time everyone can answer all the questions
Total Questions: 60
Round: Technical Interview
Experience: I attended the technical interviews for both Communication and Software profiles.
For the communication profile it's advantageous to remember transformations for some common functions.And you need to have clarity about what you are doing.The basics should be strong.
The Software interview was chill.All the questions were about basic C.And for some guys puzzles were asked
Tips: A good resume always helps you out in some situations.I kind of cupped in the Comm round.But in the Software round in the beginning of the interview itself she asked about my areas of interest and my projects.She asked me to explain in detail about one of the projects of my choice and she was really impressed with the idea of that project.After that the interview was chill only
Round: HR Interview
Experience: The HR round was just a formality.He called me and informed that I have been selected in Software profile and the location will be Hyderabad.Other than that nothing was there.
Although for some of the other candidates they completely asked about the resume and some routine questions
