The Roblox interview had three stages.

First were two games on Roblox itself: the car and factory games.

For the car game, the highest score for both maps is 6 cars. You have to try to attach attachments to cars for different terrain.

The second (factory) game involves factory lines where you need to optimize to get the most money possible (max is around 280k, but aim for 200k+).

Finally, there's the technical part with two questions (around LeetCode hard difficulty).

For the technical part, I was asked a LeetCode hard equivalent.

It was a window substring question. Given two strings of lengths m and n respectively, return the minimum window substring of string s such that every character in t is included in the window.
