I was interviewed on-campus for HARDWARE ENGINEER (VLSI) role at Qualcomm
Interview Process
Resume Shortlist Test HR Interview
Round 1

Resume Shortlist

Interview Experience
I had a standard 2-page resume as per the standard format required by the institute placement cell. The areas of interest that you mention in the resume should change according to the job profile being offered by the company.
Round 2

Test

Interview Experience
The first round of the selection process for Qualcomm was an online written test. I decided to appear for the hardware engineer (VLSI) profile. The test comprised of three sections. The first two sections – general aptitude and basic programming (C/C++) are same regardless of the profile you choose for the test. These two sections are quite simple. The general aptitude section comprises of objective questions like which figure will follow the given pattern and some other logical questions. The basic programming section consists of simple questions based on C/C++ like what would be the output of the given code, some questions on algorithms and sorting.

The third section is although said to be based on VLSI, but most of the questions asked are from analog electronics, digital electronics and microprocessors. The difficulty level varies from easy to medium difficulty. If you would have revised the topics well, you would be able to answer most of the questions correctly.
Interview Tips
Electrical Engineering students should appear for the VLSI profile as its written test is the easiest of the three profiles being offered and most of the questions in the written test are based on topics that are covered in the Electrical Engineering curriculum.
Round 3

HR Interview

Interview Experience
After the written test, the next round was an interview round. I worked on the mistakes I had made in interviews earlier and was a lot more confident this time around.
Some of the technical questions asked were related to:
Time domain analysis of waveform
Digital Electronics
Programming language VHDL
Some questions on the basics of VLSI
As I had already studied the subject Embedded Systems and had done a few related projects as well, I was able to answer most of the questions.
For the interview, I did put in a lot of effort in the preparation. Apart from the technical questions one should prepare for the HR type questions as well. I prepared answers for some typical HR type questions. One need not be completely spontaneous while answering questions in the interview. Having some points in your mind about what you want to say and how do you want to say it, always helps.
As I was interested in core companies and software companies, I prepared topics like C++ and Data Structures and practiced questions available on the internet.
Interview Tips
Although I graduated in Electrical Engineering and the company’s work is more into electronics, I was still able to get through because I was able to answer the questions asked and hence prove that I have the necessary skills. Your branch wouldn't be much of a problem during the selection process, if you are able to prove that you have the necessary skill set required by the company.

Skills Tested

    General Tips
    I started preparing for placements in the month of November. I revised topics like Electrical Machines, Microprocessors and Digital Electronics from my own notes. The notes or standard text books are sufficient to prepare for the selection process of any core electrical/Electronics Company.<br />
    Also apart from some standard textbooks, one can always search on the internet for questions, either general or specifically those that have been previously asked in that company’s selection process. Questions asked in the interview are more or less the same as those found on the internet.For the written test, revise data structures C/C++, methods of sorting, basics of algorithms, operating systems etc. For the interview you should revise embedded systems, basic electronics and digital electronics.
    Motivation for applying
    I got to know about the company profile from some of my friends and seniors working at the company. I also browsed through their website.

      I had my software interview (C language, OS ,ds) first. the questions asked in the software interview were from the following topics : virtual functions, virtual memory concept,paging concept, segmentation. oops concepts like: inheritance, polymorphism, operator overloading. In the end I was asked to write code to reverse a string and use the concept of dynamic allocation in that. I was not fully satisfied with my software interview, but i answered good amount of questions. 

      In the DSP interview questions were: 
      1) how will you generate rectangular wave. I gave them 2 solutions: a) using schmitt trigger circuit. b) by interfacing a DAC with microprocessor and using software delays of appropriate time period. 
      2) describe the nyquist rate condition and condition for no aliasing to take place. 
      3) write the expression for reconstruction of a sampled signal.
      4)when to use IIR and FIR filters. 
      5) what are the advantages and disadvantage of IIR and FIR filters.
      6)what is linear phase in FIR filters.
      7) they asked me about the workshop in IIT,madras on BLACKFINN processors.

          Round 1

          Test

          Interview 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 2

          Interview

          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.<br />
            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.<br />
            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.<br />
            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,<br />
            Computer networks, and most importantly subjects of your interest <br />
            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.
