- All information about an employee is in a resume
- There is no difference between employers besides salary
- Working for less than maximum achievable salary means one is "underpaid"
edit: Big surprise, I went to the Paysa website and their main sales messaging is Get Paid What You Deserve - Paysa market data shows that 36% of professionals are underpaid relative to market. So this article is basically "Paysa publishes report saying that you should use their service to get more money." Flagged for spam.
