For me alot of time is spent in the upfront work of the sale as well as the actual testing. We have the sales staff to do it but the actual testers are always involved in the sales process from the beginning. We do everything from the proposal, billing, testing, report writing, and presentation, our sales staff only gets the leads. In some of the larger organisations they have staff dedicated to some of this stuff as well as dedicated people to write or help review their reports so I am assuming that if you get into a larger consulting firm you would get more face time testing. On the other side if you ever want to go out on your own you will need the other skills as well. I would say that I spend on an average week 30% testing, 20% selling, 25% report writing/presentation and reviewing others reports, and 25% work in lab environment testing tools and methodologies and reviewing information similar to this forum and others. On average I am doing 2 or 3 internal tests a month at 3 - 4 days each and 4 or 5 external tests from the office coming across the internet at there firewall and public facing DMZ.
