Pros
Since the acquisition of Hilton by Blackstone, it's hard to remember the best reasons for working at Hilton. This company used to be very progressive and always had an open door policy. Outside of the recent changes, one of the biggest reasons i've remained at Hilton over the years was the ability to advance. Hilton usually will hire from within when jobs are available before they start looking outside the company. I feel like Hilton has been great for providing their employees with a great training ground and allowing you to get personal training in your current profession. The best reason of course is the huge discounts on hotel stays.
Cons
The downside of working for Hilton is the huge difference in salary compared to other companies. Hilton seems to consistently fall behind in fairly compensating their employees, cost of living raises, and appreciating loyal long-term employees. They will not try to retain an employee who has worked for the company for 10+ years, and would rather let them walk than even ask what it would take to keep them. The company is currently going through a huge "secretive" restructure. Even though they claim to be open and honest about the direction of the company, the general population knows we are all being lied to.
