The first hr interview was ok, although the hr didn't have much experience.
I suspected that this is a startup that likes to negotiate hard on salary since that is how they make money.
Everything became clear when I talked to people at the startup who had really negative behavior and denied answering to my questions.
The funny thing is that I met an arrogant person who acted like he owns the startup but actually worked with sales. I mean really?
The startup hires cheap workers with no skills in the job role, who have no idea how to do their job.
This is all the red flags I needed to completely reject this startup as I had half a dozen better offers.
