Qualcomm experience The recruitment process consisted of 4 rounds. Round 1: (Online MCQ Test) The test had 3 sections – Aptitude, Technical and the last section was respective of the course (CSE, ECE and EEE). Each section had 20 questions carrying 1 mark for correct answers and 0.25 negative marking for wrong answers. Time allotted was 90 minutes. Aptitude was easy – average with questions providing details about a situation and answering questions based on it. Technical section consisted of questions from OOPS concepts, Data Structures, Operating Systems and 2-3 questions about the logical gates. Third section (CSE) consisted of Input /Output questions from C, C++ and questions asking about the properties of certain concepts. I was able to attend on an average of 13 questions from each section. They selected 75 people for the next round from about 500 people. Round 2: (Technical Interview – 1) The guy who interviewed me was cool and friendly (He offered me banana chips). I handed him my resume and he was slightly impressed with the number of projects I had done (5). I had provided Play Store links for the android apps and so he was able to see my projects. He asked me to explain about the project which I did for around 10 minutes and I even asked for some suggestions from him about the project which made him be more interested in me and my projects. He asked me to explain what machine learning is and I explained it along with my project. He asked me if I knew about wireless networks for which I said no and he was like “cool, no problem”. I guess he was expecting a genuine answer rather than blabbering something. Then he asked me why do we need different data structures and I said data needs to be stored differently for different applications (Ex Stack for displaying messages, Queue for printers). So this round went smooth for me with questions only from my resume. Round 3: (Technical Interview – 2) This round had 2 interviewers, thank god I had 2 copies of my resume. They were happy that I gave each of them a resume. They said we know about your resume tell us what you know in the core subjects. I said Data structures. They asked me what the worst case search time complexity of BST was. I said it will be less than the number of elements in the tree. The interviewer was like, “what about a right skewed tree?” I said by rotating it we can reduce the number of searches. He asked me to prove it. So I made some rotations and showed him the tree diagram, he was satisfied. He then started asking questions from Operating Systems. He started off with what is the difference between process and threads, why should we create threads instead of new processes, what is deadlock, how do you solve deadlock, difference between mutex and semaphore. All these questions were asked from my answers. After few questions he was satisfied. Then the other guy asked me to write a program on, 2 numbers namely X and Y are given. Find the X to the power of Y. I wrote using for loop. He asked me to simplify it. I thought for a while and said we can use dynamic programming and store the values of the previous powers and use it when needed. He was satisfied. He then asked me if I knew what variable arguments was and how will make use of it. I said we can use Ellipse (…) operator. He asked me to write a prototype. I said I know it only theoretically but I will try. He asked me how you will access these variable arguments. I thought for a while and offered some solutions. He was not satisfied with it. So I said I don’t have much idea and the interview was done. 25 out of 75 people were selected for the next round. Round 4: (HR round) The HR was very friendly. I was the last person to attend the interview. She asked why I chose engineering, what inspires me, why should I hire you and some questions about my family. She then asked for my work location preference and I said Bangalore with a reason. She was satisfied. Finally only 2 people were rejected.
