                It contained 3 sections: Aptitude Questions, Programming questions and third section depending on which profile the candidate is opting for, which contained CS,VLSI or DSP profile. Programming: Pseudo code questions which required to find the output of code or the code which resulted in specific output.
                Interview Tips
                Answer all questions since there was no negative marking (at least this time).

                  Interview Experience
                  I had three interviews out of which the first two were technical and third H.R. The interview started with a personal question. Then I was aked about my project in detail. Knowing what projects you did and basic details which constitute the base of the project is must. The next question was about designing a FSM. And the following interview was based on general VLSI based questions mainly setup-hold time, power consumption reduction techniques etc and some puzzles.
                  Interview Tips
                  Knowing the basics about subjects and projects is most important.

                  Skill Tips
                  For VLSI part a HDL is needed and knowing software related to VLSI CAD is added advantage. Also good logical ability and problem solving skill helps since they ask puzzles and digital design problems.

                  High CGPA is helpful but your answers in interview are

                  more important.

                  Test Sections
                  • Section 1: Online test (Either VLSI or DSP along with math)
                  Interview Experience
                  The placement website mentioned that you can choose either the VLSI stream or the DSP stream and the online test was held accordingly. I wrote the DSP test and I was prepared only for a DSP interview and I was feeling pretty confident. However during the interview I was told that the Bangalore plant hires only VLSI Design engineers, so I decided to give it a go anyway but my lack of preparation led to my doom.
                  Interview Tips
                  I didn't use any online content, the curriculum covered by the EC dept. is sufficient.

                      The overall experience is a pain for people who have specific interests. Do not rely on information available on the placement website and wait for companies especially if placements are not your top priority.

                      My suggestion is to prepare well for the first few companies and get placed soon. You can sit off campus for companies you really like if all else fails.

                      Interview Experience
                      Aptitude and programming questions were easy but needed speed and accuracy. Technical round had questions from the profile we selected (hardware or communication or software). I chose hardware which had questions from digital electronics and solid state devices. Third section had lengthy questions but less time. So attempting perfectly the questions you know is better than spending time on all the questions without fully solving.
                      Interview Tips
                      Technical round was tough given the time constraint. So be well prepared for it

                        Be clear with the basic concepts of the subject. Be confident and don’t feel nervous while answering. Write a genuine project in your resume as they may ask you everything about the project.
