I applied online through Stack Overflow. The next day, I was contacted by HR, who explained the selection process.

The first step was a coding test on HackerRank. A Skype interview was arranged a few days later.

During the interview, I was asked to connect to a server using SSH. My screen was shared with the interviewer, and he asked me to solve two questions. I was asked to edit, compile, run, and debug the code.

Two more interviews were scheduled. They were similar to the first one but with more complex questions.

The interviewers were friendly and very professional. Each interview lasted for one hour.

After the third interview, I was asked to present three referrals. The company checked all three referrals.

String formatting

Sum of all elements in an array

Find the missing element in a sorted array

Write a function to test if a word is a palindrome

Implement functions to manipulate a stack (push, pop)

Spin locks, thread synchronization
