Gave 2 rounds of interview, in first interview questions were basics from C, RTOS and projects added in my resume. 2nd interview few C problems (DSA), OS and about my projects. After the interview HR ghosted me, I send 2 follow-ups mail and tried to contact HR, he didn't even used his energy to respond my calls and mails. Such unethical act from HR, even if I not considered one response from HR won't consume half of their lifespan.
