This question is asked to gauge your hands-on experience and proficiency with the tools and environments used in firmware development. When answering, mention specific Integrated Development Environments (IDEs), compilers, debuggers, and other tools you have used. Provide examples of projects where you utilized these tools and explain how they contributed to the success of the project.
Example Answer:
"I have extensive experience with several tools and environments essential for firmware development. I frequently use IDEs like Keil uVision and IAR Embedded Workbench for ARM-based microcontrollers. For debugging, I rely on JTAG and SWD interfaces, and tools like Segger J-Link. I also have experience with GCC and Clang compilers for cross-compiling firmware. In my previous project, I used Keil uVision to develop firmware for a consumer electronics device, which improved the device's performance by 20%. Additionally, I utilized Segger J-Link for debugging, which helped identify and fix critical issues early in the development cycle."
