Before even that, I'd rather see salaries posted. Only a disappointingly small number of companies post salary information.
In my company, it's very rare that we'll have a need that's so specific that we could actually know the salary within $10k before we hire. It's far more common that we have openings for "Software Engineers", and we end up hiring one very junior, one very senior engineer, and some folks in between. Thus, from the same ad, compensation could range from $90k w/1,000 shares to $280k w/20,000 shares. And, frankly, saying…
I have a question, are the job ads written in a way that would attract both a junior(I'm picturing 1yr out of college experience) developer and someone who is so experienced to justify a $300k comp package?
Without some clear distinction in the ad I'm having a hard time figuring out how it could appeal to people on both ends of the spectrum.
