Pros
Laid back, nothing is a rush. Management comp package is fair on salary, average at best for total comp. If you like using your own car for business you can turn your car to passive income, recognize your risk of liability if you do this. Nice offices for senior management.
Cons
Laid back work environment means average work quality delivery to clients from your support staff. No comp package or benefits beyond a small 401k match, so go in high because that is all you can really negotiate on. You can get a division of a fraction of a sub 1% of total sales if you come in as senior management on bids you lead and win, but the senior VPs divide the pie first. So it sounds good to go win a bid and make your fraction of a percent, but when the rubber hits the road you are just earning a bonus package you could have somewhere else. If you don't want to use your own car for work you will get push back. This is a transfer of liability to your own insurance in lieu of having the company insure your activity while on their payroll. I use company rentals and get an attitude and am discouraged from doing so. But I am not paying a $100k claim if I'm driving to a client meeting and get in an accident. No loyalty. I have seen 8 senior project contributors/managers with 15-20+ years with Jones-Stokes get laid off or have hours cut if the office profitability is not good. So you need to perform or earn your salary plus a 3.3x in contract value or billable hours ($100k needs to bring in $330k in business development or billable work to stay off the chopping block). High turn over at all levels, even VPs jump to direct competitors. Only dead enders stick around, no promotions for those folks.
