BBD is right, tons of INFOS under the menioned post. Anyway here's a readers Digest version of what is written there.
1. First and last days are working days, so depending what your gateway is you might have an early start and a late coming home. Average you are either home for breakfast on day 1 or home for dinner on day 6. If you rely on it it will not happen

. . .
2. Its work. Average of three sectors a day. Saturday normally quiet as well as certain month. Summer busy. Limited by 55 dutyhours per tour / week. Rarely hanging around. You might end up dead on day six on certain tours. On some few tours you come home nice and tender.
3. Mostly the standard Hilton / Crowne Plaza / Holiday Inn stuff, but due to the nature of the operation (Short notice bookings to busy places) you might end up in lower standard. Rarely in higher. But generally oka-ish hotels close to the airport. Always a new place every tour so charming ones in remote places as well.
4. Always breakfast. Crewmeals if you are flying during lunch / dinner hours. Cold meals on the short haul; nice and warm with the big boys and girls.
5. Bravo / 400 / XL generally central europe. 800 / 2000 classic centraleurope / russia and middle east. 2000eZ, 900, G IV, GV worldwide. . Bravo and 400 no APU. No influence on assignement besides the fact, that lowtimers go on the longhaul to collect hours.
6. Tax might be a mess. Generally good for the Island, bad for the frog-eaters and a few more countries. Majority seems to be happy. 25 % in Portugal and 5 % NI in GB.
7. Right. Your country.
8. Depending of the duration of your leave request two wrap around days before and after which do not count for your quarterly workday limit.
9. Maybe Perry Cars in London
10. Depends what you want. Colleques excellent! Flying is great, second to none. New Jets, nice ones in the pipeline. No calls during days off. Good support generally, some departments can not cope with the growth. BUPA insurance. No Loss of License (should come soon they say), unclear pension plan, no union reps, no clear seniority. Ugly ties.
Hope this helps, tons of reading materiel in the BIZ-Jet section.
And you have to meet SMEAGEL.
