Interview Preparation Tips

Round: Test
Experience: The first round was a written round. The paper had three sections: Aptitude , C and DSP.

Round: Technical Interview
Experience: 14-15 people were shortlisted for the second round (Technical Interview round). Questions were asked on topics like Digital System Design, DECA and VLSI (Sequence detector questions, FSM based questions and MOSFET based questions)

Round: HR Interview
Experience: 3 people were shortlisted for the HR round. The general trend is that, you make it to the HR round, You have almost grabbed the Intern :) . Usual questions like "why Qalcomm?", "What is special about you?", "What are your strengths and weaknesses?" etc. were asked.

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.
Skill Tips: I went through DECA notes. No need of any extra preparation if you are thorough with basic concepts in DSD and DECA.
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.
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
The overall recruitment procedure was Exhausting. It lasted for an entire day.

Interview Preparation Tips

Round: Test
Experience: Online test consists of 3 parts: 
1) Aptitude 
2) programming (C/C++, Data Structures) 
3) Technical. 
No negative marking. Apti and programming parts were easy. There were three different technical sections forthree different profiles: 1) Hardware 2) Communication/DSP 3) Software.I appeared for 2nd profile. In this, the technical section had question mostly from DSP, few from communication, analog circuits, digital circuits etc. Each section was given different amount of time. Time for the Technical section was less and I felt that this section was the deciding factor in short listing. There was a CGPA cutoff of 7.5 . My CGPA was 8.75.

Round: Interview
Experience: There were 3 rounds of interview out of which 2 were technical and 1 was HR round. Asked about thesis, term papers, trainings, and question on Digital logic circuits: to design FSM, designing simple logic circuits, delay & its calculation in the digital circuit, MOS etc. Few communication related questions, some puzzles and apti questions. In HR, they asked common HR questions like about yourself, Why qualcomm, training experience, any specific location preference etc. both the technical rounds were almost 40 minutes long and HR was 20 minutes.

General Tips: 1) Should be clear about your M.Tech thesis, B.Tech project, summer training, Term papers. Understand their terminologies and concepts since almost all companies ask about it.
2) For aptitude preparation, solve the material available in preparation portal, can see for online aptitude tests and puzzles and along with that appear honestly in the mock tests organized by SPO. Aim on accuracy and speed.
3) For Programming preparation, revise basic concepts of C and DS, you can use book by Denis Ritche, Yeshwant Kanetkar. Solve online mock programming tests, so you get aware of standard questions andmost common mistakes. Try to write some codes while preparing so that you will be confident writing infront of interviewer, especially of DS like linked list, trees, sorting, searching etc. I did not prepare for OS,but most of the software companies do ask questions on it. Galvin is the standard book for OS.
4) Technical: very vast field includes all the course and practical knowledge you have been studying. Basicconcepts should be clear. Prepare Digital circuit design, Communication, Wireless Communication, DSP,
Computer networks, and most importantly subjects of your interest 
5) Do prepare in groups, it will help you in clearing your doubts and also it will improve your interview skills. Mock interviews are also organized for your confidence building.

Interview Preparation Tips

Round: Test
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.
Tips: I didn't use any online content, the curriculum covered by the EC dept. is sufficient.

Round: Other 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.
