They contacted me through a university recruiting site and invited me to apply for the position. You were able to mark whether you were invited to apply by a recruiter, and this sent you straight to getting a phone interview and coding challenge.

The coding challenge was through a proctoring website (ProctorU), but they forced you to contact the proctor every time you clicked outside of the tab. This was annoying if you don't have every single small detail of the coding language you're using memorized.

The coding part was three parts:

• One was how many problems you can solve in 2 mins (mathematical, logic puzzles).
• One was learning to use their made-up language with multiple-choice questions.
• The last part had 4 coding questions.

If you have a CS background, you're only allowed to use Java or C/C++.

They say you should only need basic data structures and algorithms, but their coding questions required DP knowledge.
