The phone interview was straightforward and pleasant. Although the email stated it would take 15 to 30 minutes, it went over an hour (not a big deal since I had nothing going on, but for someone with a busy schedule, I could see that being an issue).

The interviewer was polite and professional.

The technical interview was very difficult and was a proctored exam consisting of three sections.

• The first section requires you to answer as many fairly simple math problems as you can in two minutes. Have a handheld calculator prepared in advance and brush up on your algebra.
• In the second section, they teach you a made-up programming language and ask you some questions along the way. It wasn't that bad, but aspects of it could be confusing.
• The third section was four LeetCode problems, which were quite tough.

To add to their difficulty, the coding has to be done in a plain in-browser text editor with no tools or support.
