The interview was virtual and very easy. However, I fumbled some theory questions. I was asked very basic questions during the interview.

The interview duration was 1 hour and 30 minutes. The interviewer was really friendly.

Brief introduction of myself.

I was asked about Linux commands: How to find a directory? How to display all directories? How to find the administrator of the PC?

Then, she started asking in-depth questions. I told her to switch to other skills on my resume. She switched to OS:

• Process vs. thread
• What is a context switch?
• What is segmentation?
• What is swapping?
• Primary memory vs. secondary memory?

Then, she asked me to open Notepad and posed programming questions:

1. Valid parenthesis check.
2. Sort numbers using any sorting algorithm.

Behind the scenes of C compilation:

• What is strcpy(), strcat()?
• What is malloc and calloc?

Then, she asked me to open the compiler and asked:

• Swap two numbers without a third variable.
• Reverse words in a sentence.

I had mentioned Python on my resume:

• init and del?
• Lambda function.
• Global vs. static?
• Why do you use Python?
