Well since no one has weighed in on the the USN pointy nose side here you go:
Once you finish 3 yrs of traning(2 yrs training command/1 yr FRS) you'll get assigned to a VFA squadron either in Oceana, VA, Beaufort, SC, Lemoore, CA or Whidbey Is, WA(F/A-18G) or Atsugi, Japan for 3 years.
While there are no 'set' hours, day to day ops for the most part while not deployed are pretty standard 0730-1700ish. Of course you may brief earlier than that and fly later than that on any given day. Most day's you'll fly once perhaps twice. Normal sortie length is 1.0-1.5 depending on the mission. Briefs are usually 2 hours prior to launch and debriefs are usually complete 1.5 after landing. Certainly there are exceptions to those times.
You also have to figure in your ground job. You'll either work a ground job in OPS/Maintenance/Safety/Training. Each job is a bit different from a time requirement standpoint, but suffice it to say you're busy. The QOL in a squadron largely depends on the front office and department head leadership as well as the fellow JO's in the squadron. They will either make your life miserable or make it fun/enjoyable to be there, that is purely a crapshoot. One other factor to consider is whether you are in a single seat squadron or two seat squadron. 2 seat squadrons basically have twice the aircrew for the same number of ground jobs. Some argue that there is less work, others argue the opposite. Over to the two seat guys to answer that one. That's a double edged sword and you have to deal with the WSO's. Bottom line 10-12 hour days are pretty routine for 3 years. Expect to be deployed for at least 1 total year of that three minimum.
When you're on the ship, life is just the same, BUT you're on the ship! Days tend to get longer and blend in. On the ship you'll fly once a day when the air wing is flying sometimes twice. One paragraph can't give you the wallet sized photo of the big picture.
As for hours. Most guys will leave their first fleet tour with around 900-1000TT. The beauty of that is, once you leave the FRS all of it is ME PIC.
Your options from there are to be assigned to any of multiple training and production sources(FRS, Training Command, Weapons School, TOP GUN, Test Pilot School, etc.) as an instructor where you will build even more time, and not deploy. Some of those jobs are very laid back, alot of home time while others are very busy and time consuming but also very rewarding(totally depends on your niche/desires)
If you're looking for a job that just allows you to fly and go home, I would look elsewhere, and definitely not look in the military.
Hope this helps.
