AIR COMPANY interview questions

First-round interview with HR and discuss the future of aviation fuels and the scope of it, the team size and what department will I join. Good vibe and culture. Second round will be technical interview with HM on technical problems

I had three interviews, all of which went really well, or so I thought. I ended up being ghosted at the end with no formal rejection or final email. I think after three hours of my time and energy, a simple "thank you but we're going in a different direction" is bottom line respect.
