What's the most frustrating part of the modern job application process?

I've been building ResumeUp.AI to help job seekers, and the feedback I get is wild. Some recurring themes:

• ATS systems rejecting qualified candidates over formatting

• "Easy Apply" leading to 500+ applicants per role

• No response after multiple interview rounds

• Job descriptions that don't match actual roles

For those hiring, what's broken from your side? Would love to understand both perspectives.
