North Embedded Software Engineer interview questions

Online Coding interview first, give 1.5 hour for 5 subjects questions and 1 coding questions, e.g. rewrite C functions for log read/write with C++, by considering concurrency scenario.

I dont know how difficult or easy the interview might have been if I had made to that stage. The recruitment process in this company is probably the worst I have ever encountered in my life. I applied online for this job and after a long while was contacted by one of the co-founders named Aaron Grant. We talked over email and setup an initial phone interview. I took half a day off from work because of the time difference but Mr.Co-founder never called.I waited like an idiot for an hour and sent him multiple emails. He never had the decency to at least reply to my emails.
