Question

3.
The company wanted
candidates need not apply for the job.​

Answer 1

The majority of employers do not give official feedback to rejected interviewees. There is a simple, legal rationale for this: it reduces the potential for getting sued. Informing a candidate of why they didn't get hired can open a can of worms.

By all accounts, you think that you're more than qualified for the position. But when a potential employer reads your resume and cover letter, they may have a different opinion. ... But technically, a company might not legally be able to tell you what's wrong, so the employer likely won't respond to your application.
