The onsite interview was amazing. You first arrive and sit in the main lobby for about an hour. Here, they want you to interact with some of their amenities, such as playing video games on their Xbox One. They offer free coffee and drinks while you wait to help you relax.

After this, you talk to a recruiter who explains which team you'll be interviewing for and how each interview will proceed.

The interviews were quite good, with semi-difficult questions. Most questions were based on strings, with a couple of graph theory questions included. Some questions also relate to your resume experience.

If you are walked out after lunch, the process is over. During the last interview, you will speak with your potential future manager.
