I am doing my B.E. in ECE at Madras Institute of Technology in Chennai. I applied through on-campus recruitment.

First, we had an online test which contained aptitude, digital logic, and some C programming questions. After that screening, I was called for an interview (it also happened in our college campus).

There was only one interview with some simple questions. My interviewer was very friendly. It was more like a conversation than an interview. He asked me to ask any questions. I asked, "What does a test engineer do?" He made me answer that question by asking me some questions. He also asked me about the online test, such as "Which question did you find challenging?"

Draw NAND gate using CMOS. Then convert it into AND.

Write a program about pointers and explain it in C language.
