hey advertise the field as competitive with good wages. This drives more people to apply along with the current state of economy. A lot of people of particular apply so they justify raise the standards. If not many people meet the standards, then it justifies hiring foreign labor / outsourcing work so who's the cheapest of labor? Asian/Latino people. Which of those groups is educated, Indian people with some Filipino labor here and there. With that said, FB doesn't have anything to lose out being sued. They can take whatever they get and continue in the same manner.
Whoever was complaining about getting work, your feelings are justified. Big tech has created this standard and it's mimmicked across a lot of companies.
