My interviewer was focusing a lot on this as being from ECE branch, I had not done any project related to ECE branch. I had to explain it to him that, while assembly language programming was being taught to us in my college, I came across ML, python. I found that to be more interesting, that's why focused more on that. See, you have to be genuine and honest to the interviewer. Don't try to give some plagiarized answer off the net. You can never predict the next question. These type of questions are always asked in interviews its best to just answer them honestly and try to give a good reason for the choices you made in your college related to your career.
