I applied on their career website.

A week later, I received an email from HR to set up a technical interview.

The interview took one hour and covered pure technical questions. The interviewer was the lead of the group, and he was very nice and professional.

I tried my best but did not pass. Three days later, I received an email stating that they had picked another candidate.

RTOS: Processes vs. Threads How to handle thread conflicts.

C Programming: Manipulating strings. Linked list traversal. const vs. static vs. volatile. Etc.
