Everything related to memory management. what are the elements in rtos. there will atleast be 4 rounds in their interview process.

The interview process lasted for three hours, during which they inquired about all the projects I had worked on based on my profile. They were trying to extract information that was relevant to their work. I have mostly worked on the application side of development for L2/L3 routers, WiFi routers, and WLC. During the interview process, I shared my experience with them, but after three hours, they informed me that my experience was mostly in application development, whereas they required low-level coding knowledge. During the "tell me about yourself" section, I had clearly explained that I was not a low-level firmware developer
