Hi everyone, I applied to Roblox's summer internship opportunity last week (sort of as a joke because I thought I'd be instant rejected) but just received an email inviting me to the next step of the interview process, the online assessments. For context, I have years of coding experience on Roblox (luau) which I made sure to include in my job application. Also, while I am still a highschooler, I did already commit to a university so I included that as well. Is there anybody here who has taken Roblox's online assessment? What should I expect out of it? Is it difficult, easy, or somewhere in between? Any tips would be greatly appreciated!! :) (I tried signing up for the Speak thing but the URLs wont load)
