I was contacted by the HR of the company. The process was straightforward, consisting of a phone interview followed by an on-site interview. The phone interview was a process of getting to know each other.

Two engineers interviewed me during the on-site interview.

• The first engineer asked some general questions, such as how to shuffle an array (programming) and other OOP concepts like the difference between an instance and a class, what a constructor is, inheritance, abstract classes, and pure virtual functions.
• The second engineer asked me to retrieve several email lists from different URLs and return email addresses that occurred multiple times across these URLs. The email addresses were stored in JSON format in the URLs. I used a Python package to retrieve the information.

Everything went very well during the interview. I solved the problem quickly and was told by the HR that a decision would be made in a week.

However, I was declined a month later after sending a couple of emails to the HR.
