After about 2-3 years, the excitement wears off. The free travel is wonderful, but if you have a family or are serious about career growth, that becomes less of a sticking-point. There is extremely little room to grow, get promoted, and make more money. I worked at EF for almost 4 years, consistently hit sales goals, brought in over $1 million revenue y/y, and never made more than $60k/yr. Do not take this job if you're used to working commission-based sales, or at least be very aware of what your salary will be. Whatever they tell you you can expect in bonus, half it and that's more likely. Goals will never be less than 10% up y/y, even if you have a giant book of business. That means, the longer you stay and the better you do, the harder it is for you to make money.
They also never let managers, or EF-lifer's, go (barring economic distress like covid). Managers are often shuffled around from office to office, department to department, even though they really don't contribute any longer, or are down-right terrible at their jobs and impact the company morale. If you can survive 7-10 years you're practically untouchable.
If you're considering EF, and you're used to a typical Sales salary - look the other way. Or at the very least be prepared to take a large pay-cut. If you're recently out of college, looking to learn a lot, have a ton of fun, meet lots of interesting people, and make just enough to be $100 away from living paycheck to paycheck, this is the place for you!
