      Round 1

      Test

      Test Sections
        Interview Experience
        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).
        Round 2

        Technical Interview

        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.
        General Tips
        High CGPA is helpful but your answers in interview are

        more important.

        Test

        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.
        Round 2

        Other Interview

        Interview Experience
        Make the interviewer ask you questions based on your strengths. They only try to assess how well you can understand something you actually like.

          General Tips
          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.

          • Section 2: Programming basics (30 min)
          • Section 3: Technical Section (30 min )
          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
          Round 2

          Technical Interview

          Interview Experience
          Basic questions from digital circuits like working of flipflops,FSM design, mux from logic gates, counters and frequency dividers etc.
          Also questions about my project mentioned in resume. After that a little chat about the kind of work and the projects there.
          Interview Tips
          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.

          Interview Experience
          Asked to summarize my resume. A small conversation about my interests. I was asked how I came to know about Qualcomm. Then they asked if I had any doubts and later informed me that I was selected. It was a very friendly interaction.
          Interview Tips
          Knowing a little bit about Qualcomm may help.
