It depends on the airline and the type you fly. Virgin is LH only, Ryanair is short haul only, BA does both. There are exceptions but generally bigger types can go further, and once you're more than about 5 hours from base then you're generally staying in a hotel. For a first jet job most people go short haul on the smaller types (A320/B737) because there are so many of them. Some companies do take cadets in the 777 etc starting a cruise relief pilots but generally LH flying tends to be a second or third job. You don't get a lot of landings doing LH.
