3M Technology Senior Software Engineer for MERN Stack interview questions

I got a call from Malkesh Mangukiya who is CEO of this company. And after He asked for my salary Expectation, He used to talk to me very rudely. and he cut the call. I thought he will be an HR who is frustrated with the company. But after checking on their Website I got to know okay he is the CEO of that company. Now I'm shocked at how a CEO can have this rude Attitude. I will suggest you guys Never Join a company like this.
