This is such a big hyperbole that I'm just gonna call bullshit on this.
A few interesting things that I’ve experienced:
- Companies tend to like me enough that they keep asking me back to “meet more people” - a very time-wasting process that often ends with silence (and no returned emails or calls)
- When rejected from a particularly interesting company, I will sometimes offer to work for free or a discounted rate initially, just so I can prove what I can do. No one has ever taken that offer.
- I have even offered to work at a very discounted salary, on par with a new grad salary. My rational is that I’ll still make more than I would at Whole Foods, and I’m confident that they’ll be impressed enough to bump me to my normal salary. No takers. Although one company did say that by hiring me, I would “cause more harm than good”. WTF?
And don't let anyone squeeze you to make your actual rate lower. I once went to an interview where I was told that the expectation would be for 45 hours of billable work per week, and so I immediately told them that my salary expectation for that would be 20% higher than for a 40 hour work week. They could raise the salary, or lower the work hours, because on a per-hour basis, their pay range was suddenly no longer competitive.
They declined to negotiate that. So I eventually went to work for someone else more willing to pay me what I think I'm worth.
Don't work for free; it just encourages those who try to scam free work out of people. The only person for whom you should be doing unpaid work is yourself.
