One thing that is interesting with these "always hiring" shops - Do you have a high turnover or do you constantly extend the office space?

We don't have high turnover. We're in a rapidly expanding field (demand far outstrips supply in software security), and we're selective, by which I mean we could grow a lot faster than we have over the last 8 years if we elected not to hold quality constant.

It typically means they're always willing to hire, provided the fit is right.

The specific technical answer in our case is: if we have a headcount cap, I don't know what it is.
