1.) client facing role in finance industry
2.) Yes and no. Enjoy more when it is a multi day stay in one location. Hate when it is same day trip waking up early and flying home late, or a long trip but different country each day.
3.) Wouldn't and shouldn't be a consideration as you're young and probably dont have kids. Make no mistake that travel is an inconvenience not a perk, and make sure that you are getting adequate compensation for it. Always strikes me as odd when some people I run into consider it a benefit. I definitely liked the idea of it more before I started than I do now, and I'm only 31 and no kids
4.)
I do 2-3 months a year away, but in the form of a small number of longer trips (typically 1-3 weeks). That may or may not appeal vs a higher number of shorter trips depending on your personal situation and preferences. It's also nice to sometimes take a vacation on the back of a biz trip.
