It was a telephonic interview. The first person called and asked questions about Linear algebra, impulse response and Probability. He asked nearly 4 to 5 questions. Then another person called in 10 minutes and asked questions about digital communication, signal processing. The questions were basic asked in the form of problems to understand if we can apply the concepts. Waiting for the result.

I applied online, and interviewed with 3 persons, each for 30 minutes, asked about resume and projects, and some soft questions and tech questions, about git basis, digital signal processing
