It was a standard SQL, Python, and product case interview with medium to high difficulty.
This was by far the worst interview experience I have ever had. The interviewer gave only brief "yes" or "no" responses with no elaboration throughout the process, which made it difficult to solve problems collaboratively. Not only that, she kept looking at other screens (I could see this reflected in her glasses) and interrupting my responses whenever I tried to explain my thoughts. She didn't sound excited at all and gave me a negative impression about working at Roblox.
