I applied through their website in October for a software engineer new graduate role in London. A week later, I was sent a HackerRank coding challenge.

The challenge included a single problem that was supposed to be completed in 60 minutes. It took me a lot of time to understand the requirements and the examples, and I didn't find the solution right away. By the end of that hour, I managed to complete the code and fix the compilation errors, but only 2 out of 12 test cases passed. I didn't have time to adjust the code, so it was sent as is.

A week later, I received an email stating they would not progress with my application.

The question regarded a 2-player game called "Dots & Arrows". In this game, each player could add an arrow on a 2D plane according to some rules and receive a point if they closed a square. Given the board at a certain time, I had to determine how many points each player had won.
