One online round of 1.5 hours with 60 multiple-choice questions and negative marking.

I attempted 51 out of 60.

I was shortlisted for an interview.

The interview was scheduled two days later on MS Teams. It was for 45-60 minutes but stretched a little longer.

The interviewer was nice and spent the first 15 minutes introducing himself and explaining the job profile.

After the technical interview, the HR called to know the location preference and asked one more basic HR question for formality. Only those who were going to get selected received a call from HR.

He first scanned.

Then he asked 6 questions in total: 5 from C programming and 1 from OS fundamentals.

I answered 3 out of 5 C questions and 1 out of 1 OS question correctly, but my answers to the other questions were not so good. He was probably looking for someone who could answer all the questions correctly since they were all very basic.

Output in C question:

• Find the unique number in an array that is not duplicated.
• Big-endian vs. little-endian.
• Implement prevention from overflow.
