I was approached by an external recruiter regarding an opportunity at ROBLOX. My initial phone interview was with a recruiter at ROBLOX. We discussed my relevant experience in console game development, particularly my experience in rendering. She emphasized the importance of C++ for this position and wanted to make sure I was prepared for it going into the interview process.

I asked her questions ranging from team sizes to product KPIs to company financials, all of which she provided honest and specific details on. I was particularly impressed by the level of knowledge and enthusiasm the recruiter presented throughout the process.

My second phone interview was with the Director of Engineering of the hiring group, which went into more details on my dev experience. I also learned more specifics about the project and the team from this call.

After that, I was given a take-home C++ coding test through testdome.com. There were two questions, each of which I was given an hour to complete once started. I was allowed to start the test any time during a one-week period. The questions were interesting and moderately challenging.

I was allowed to use an IDE of my choice to develop and test my code before pasting them into testdome. Testdome also provided a "Run" button, which you can use as many times as you want. This was very useful as you can test out initial solutions quickly against their test cases. Even though I did not get to see the exact test cases, it was a sufficient hint for me to iterate over my own test cases and solution. I completed and did well on this test. I thought this emulated well the process one might use to cook up coding solutions quickly in a work environment.

Due to personal reasons, I decided not to make a move from my current job yet and did not continue with the interview process after the test. Nonetheless, I had a very positive experience with the interview process. I received prompt and clear communications every step of the way, and everyone I have spoken to has been smart and enthusiastic.

How would you describe a renderer?
