17 McAfee Interview Questions and Answers for SDE | How to Crack

I’m sharing my experience attending an interview at McAfee. This is the interview for SDE (Software Development Engineer) profile. I have five years of experience.

There was one coding round, three technical interviews, and two managerial interviews. These interview rounds were conducted at their Bangalore, India office location.

McAfee Coding Test

They have given a paper. There were multiple questions and some coding questions to solve. This is a 45 minutes test.

1. There were some Python programming snippets. You have to find out the output of the program.
2. Write a program to find the sum of all the elements in the list using recursion.

(Tips: Python list is very common and most useful data types in Python. If you know popular Python list functions, you can solve most of the coding questions.)

You have to write a code in Python. You can also write a pseudocode. You have to explain your code in the next interview round.

There were a few more questions that I don’t remember now.
