Rapyuta Robotics Interview Question

In the first round, they asked me about React and JavaScript stuff, and also which tech I'd use for a project they showed me. In round 2, there was a coding question based on JavaScript currying. The third round was about designing frontend systems. Round 4 was with a manager who asked general questions, like how I deal with conflicts. They also threw in some questions about completing number series, a puzzle, and a tricky one about figuring out the Earth's circumference without knowing the radius.
