T.I came to our campus for campus recruitment, First round was a computer assessment, I had applied for digital and Embedded role The test had 3 sections for me : 1. Aptitude - 20 qstns 2. Digital - 20 qstns 3. Embedded - 10 qstns Digital was mainly about gate simplification questions and some delay time related question for a given digital circuit. Embedded role had only 10 questions it was related to C, cache mapping, and semaphores, deadlock condition. I was selected for Embedded role interview but later got rejected in the interview : In the interview there were 2 people, it was online both of them had their camera off , so i could see only myself and 2 names in the computer screen. The first interviewer asked me qstns on C and asked me to write some basic programs, He also asked me what happens when a computer boots up, I think I did well here, In the middle of the interview the second guy came and he started asking me many questions related to my core btech ECE like signal processing, he asked me about the difference between fourier and laplace transform, some dft and fft related questions, then he asked me some practical questions based on nyquist theorem , then he asked some qstns on guassian noise and so many others. As I didn't prepare for those questions and as it was very much unrelated to the job role so i couldn't perform well there.

First round was off basic core questions and questions were related to C programming Computer organisation operating system and little bit of computer network. In the interview they asked me about C programming the most and I have heard that they asked some questions related to compiler also.
