I applied online. The process took 2 months.

The interview process consists of:

• At least 1 screening with HR
• 1 interview with a team member who will ask general questions about your resume and team requirements. They will filter the candidates and usually will not ask for any complex coding.
• 1 last interview round that will last a whole day with many of the team members. If you made it this far you are very close to being hired.

The whole day interview round might include at least 3 interviews with people with seniority levels usually bigger than yours. The interviews can be technical, non-technical, coding, no coding, system design; it all depends on the team.

RTOS Basic questions, Context Switching, Schedulers, mutex, semaphores.

C/C++ Technical questions:

• Structure Padding
• register/volatile keywords
• how the compile/linker process happens from a cpp file to a hex file
