Wolverine Advanced Materials interview questions

Had a 30-minute first interview. The interview was fine, asked the basic first-interview questions. I was told I would hear back by the end of that week or beginning of the following week. Then I was unprofessionally ghosted. It really doesn't take that much effort to send a generic email to everyone that took the time to research your company and interview.

waiting for long time and short interview............ only interested in my previous and promising salary and manager has weird manners, I don't ask this kind of company.. why?? that company has no tech just import and sell products to customers
