Interesting info and interesting website. Do they pay a small fee for each W2? Otherwise I don't see the motivation to go through that whole process
The whole point is that they verify them. In contrast with, say, Glassdoor. Which is why even a singular data point can be treated as meaningful.
> For someone making $400k, a whatever fee they have to offer wouldn't be worth 15 minutes of time
I mean, sort of. I don't see that as a reason nobody would do it.
It's worth it if you can pull up the median, improving the chances of getting a better offer down the road.
