Do you tell them the salary and % of the company they’ll get up front?

% in company not a thing here. I ask for a salary range from the candidate. If that meets the range I can potentially offer, I say so. If it is too high, I also say so. If it is lower than usual and it is a final match, our offer will be higher. If the candidate "refuses" to name it (acutally didnt happend in the last years) I can only assume that I would say my budget. Guess its fair or what would you say?

Yeah, that’s fair. It’s very common that candidates get surprised on the downside at the end of the process, though, so I think it’s generally fair for the candidate to hold back some information until you’re sold on them. Though it’d be nice if they didn’t have to.

Instead of asking for range from them, why not tell them your budget first? Or at least both write them down on pieces of paper and reveal simultaneously.

99% of candidates come through some 3rd party recruiter (in our case). They know our ranges and communicate this. The other 1%, well I just dont do, no special thoughts. Its not in my intention to push compensation down. This only has future downsides if I hire the candidate and he performs well.
