During my recent interview experience, I was pleasantly surprised by the thorough and challenging nature of the process, which I would describe as "very good." Initially, I was asked about "IMU basics," requiring me to elucidate my understanding of Inertial Measurement Units and their application in real-world scenarios. This was followed by an intriguing practical test where I had to implement a "localization scan of a room," which tested both my technical prowess and my ability to handle practical challenges. Later, I was presented with several "mathematical questions" by the manager, which aimed to evaluate my analytical and problem-solving abilities. One of the standout moments of the interview was the "coding question on binary search." It became evident how "LeetCode important" preparations were, as my consistent practice on the platform had equipped me with the skills to tackle such coding challenges effectively. Overall, the interview was a balanced mix of theory, practical application, and coding proficiency checks, and I left feeling both tested and invigorated.
