Interview Experience
aptitude was as usual.
Technical was tough. lots of concepts were revisited. Digital systems, analog circuits, Computer Oraganization etc.

Skill Tips
Most of the questions test your knowledge of the fundamentals of the subjects. Once your basics are strong you can easily crack the interview.<br /> The earlier you start your preparations, you have better chances of getting through. Find some time to prepare during the summer vacation as it can earn you a great advantage. Don’t get nervous during the interview and always have a pleasant smile.
General Tips
The overall experience was challenging as well as rewarding. All the interviewers were very nice and polite and made me comfortable. Make sure to mention the topics of your interest at the beginning of the interview. Be prepared to explain the projects mentioned in your resume. If you are not sure of the answer to a question, explain to the interviewer your approach to the question as he may guide you to the correct answer. They gave more importance to problem solving approach than accurate answers.

Job profile offered – Hardware Engineer Given an opportunity to ask something to the company people, feel free to ask for more details of the profile offered and the kind of work that the profile demands.

      Skill Tips
      I went through DECA notes. No need of any extra preparation if you are thorough with basic concepts in DSD and DECA.<br /> 1) Prepare your Resume properly. I was asked about each and every project that I had mentioned in my Resume. If you fumble about anything on your resume, it will dampen your prospects of moving forward.<br /> 2) For internship selection, there will be 1 technical interview round and 1 HR round whereas for Fresh grads selection : there will be 2 technical interview rounds and 1 HR round<br /> The overall recruitment procedure was Exhausting. It lasted for an entire day.
      General Tips
      For interns: Be thorough with DECA, MOSFETS and DSD. These are the areas on which Qualcomm's work focuses on. It will be a plus point if you know VLSI.

      For fresh grads: You need to be thorough with VLSI design in addition to the above mentioned topics.
