I was interviewed on-campus
at IIT Madras for
Core role at
Test Technical Interview
No. of Questions
- Section 1: Aptitude
- Section 2: Basic programming
- Section 3: Communication
The first two sections were relatively easy. Section 1 had some probability and comprehension style questions. Section 2 had questions on C programming, Computer architecture, and data structures. Manage your time properly. Don't get stuck on a question for too long. Revise C syntax and precedence of operators for the basic programming section. The communication section was relatively tougher. It required knowledge of modulation schemes(QAM, BPSK, MSK and so on), Digital signal processing.
Manage your time properly. Don't get stuck on a question for too long. Revise C syntax and precedence of operators for the basic programming section. If you have not done a course on communication systems opt for the electronics or software test.
- Question 1: Describe an LTI system.
- Question 2: Differentiate between call by value and reference.
- Question 3: How would you find the impulse response of a system?
- Question 4: Why Qualcomm?
My technical round involved a mix of technical and personal questions. The technical questions asked were easy, possibly because the interviewer liked my answers to some of the personal questions.
Read about Qualcomm beforehand. Qualcomm allowed students to interview for any profile irrespective of the test they chose to write. Try to focus on one profile(software, hardware or communication)
Even if your test goes bad you still have a good chance of making it to the interviews.
Motivation for applying
I am interested in the field of communication and believe that I could do some work in that field at Qualcomm.
