Students selected : Ayushi Agarwal , Harprit Singh Chhabada, Sumit Verma
Ayushi Agarwal :
1) Written round: - This round basically is an online test and is divided into two profiles- one is the VLSI profile and other is the Electronics profile. The profiles have to be carefully and wisely chosen according to the level of preparation that you have in the individual profiles. If the profiles are wrongly chosen, then it will surely affect your result and your chances of getting selected.
Each profile has three sections:
 Aptitude: The easiest of all sections I must say. It has easy aptitude questions to test reasoning and analytical skills. You just need to have speed and you need to be quick.
 C programming: It has simple problems based on finding the outputs of simple C codes, some are tricky. It has some problems on finding errors and questions on types of sorting and data structures. A very deep knowledge of C and Data Structures is not required. You just need to know the basics.
 Technical: This is the most interesting section and has a higher difficulty level. I opted for the VLSI profile. It had questions of digital electronics, some questions on VLSI fabrication. You need to know the basics of communication, VLSI, deep knowledge of digital electronics and logic families. In this profile, one or two questions may be asked from Verilog/VHDL too.
2) Interview: Technical- The interview was interesting and Qualcomm has very friendly recruiters. So be confident while entering the room. I was very nervous as it was my first interview ever but my interviewer was friendlier than I had thought. In the interview, you just need to be clear about your basics. You need to be confident while delivering what you have to the interviewer. The interviewer will first ask you about yourself and in this part, just be sure that you don’t talk much and be precise and limit your answer to your introduction, your education and give a brief about your hometown. Tell about your projects; describe it in brief as to how you came up with the idea, what problems you faced and how you solved them. Ensure that you create an interactive atmosphere in the room so that the interviewer does not lose his interest in talking to you. He asked me questions related to Digital Electronics and those were basically theoretical as well as practical. He asked me the basics of analog electronics like junction diode and its characteristics. He asked me about the types of processors used in laptops. The questions were not only from the books but he also judged me on the current happenings in technology. He asked me everything about VHDL as my project was based on it. The interviewer will ask you everything related to your project so be sure you write a genuine project in your resume. Some questions were from microprocessors. Be confident and don’t feel nervous while answering. I was stuck in one question so I became nervous but the interviewer helped me with hints and brought me back into the conversation. Lastly he just asked me about Qualcomm, why I wanted to be a part of it. He asked me why I was there in that room that day. Be ready with your questions at the end as it will show that you are interested in their company.
3) Interview: HR- This is a very cool round I must say, easiest of all. After going through all the above, you just need to go and tell about yourself. He asked me about myself, my hobbies and my academic background both in school and in college. He asked me why I wanted to go for job and not for further studies even after having such a good CPI. He asked me why I wanted Qualcomm and whether there will be any relocation problem. He asked me about my family. In short, it’s just a friendly interaction. Be confident, that’s the main point.

Qualcomm provides perhaps the best benefits in the industry. Everything is paid for ( accommodation, food, transport) and you get a competitive stipend of Rs. 20,000. Each intern is assigned one mentor and one manager so you get a lot of attention. There are team outings, quizzes and the workplace itself is full of energy. Innovative thinking is encouraged and the work load is well balanced. Also it has a really high conversion ratio from an intern to full time employee.
SELECTION PROCESS :
WRITTEN TEST:There was an online test consisting of 3 sections -
- Aptitude - Pretty easy questions. Just take care of the time. You need to be quick
- C programming - simple problems on finding out the errors, guessing the outputs, what is the code doing and similar questions.
- Technical - Basics of IIR and FIR filters (Refer Digital Signal Processing by S. Salivahanan, the same book will be used in your next semester course subject), Signals and Systems (as studied in your course).
Technical: Tell them about your projects, they were pretty interested to know. I spent about 15 minutes discussing about my projects - what problems i faced and how was i able to overcome them. Interview level was medium. Just be clear with all your basic concepts, specifically in digital electronics and analog electronics if its the VLSI profile you are going to join. I was asked all sorts of questions from digital electronics like counters, XOR from NAND or NOR, etc. Some questions were from microprocessors. Also the interviewer asked me whether i had done some coding in VHDL. Be confident while answering. The interviewers will even hint you if you get stuck.
You should always be ready with questions when your interviewer asks for questions that you might be having. The recruiters should come to know that you are so excited and keen to get a job in this top notch company. Do some research about the company before your interview and also ask a couple of questions at the end. ASKING QUESTIONS SHOW INTEREST !!
HR: Pretty easy as all HR rounds. Typical questions like strengths, weaknesses, hobbies, why qualcomm, relocation problems, satisfaction with the stipend amount, etc.
Both the interviewer were very friendly. They would even help you out if you are stuck at a problem by giving you hints and starting to the solutions.
LIFE AT QUALCOMM : Awesome relocation. You will be provided with both ongoing and return flight journey tickets with pickup and drop service in Bangalore.
