Pros
Fair pay, not high or low. Functions at the facilities, mainly put on and organized by employees, but the company does add some to it. Can sometimes work from home, but this is largely used to get 12-16 hours a day and weekends out of people.
Cons
The running joke at HPI among thousands of employees is, "The work / life balance is that work is your life now. That's the balance". Prepare for required overtime, required working on Veterans Day (even if on a Saturday or Sunday), required working every single day straight for 19 days in November including Saturdays and Sundays in many departments (although not all). It's not a one time event, they actually plan to do this every single year. If you do not work overtime, you cannot keep up with workloads as they purposely plan to give more work than employees can do in 40 hours. Required working through vacations! Even on vacation, most positions it's required to check and respond to emails, even do file work for your position. I have never once had a real vacation off and a couple of them turned into regular 12 hour working days that I never even got to see my family except at dinner. Very strong political views. During the election I received more emails from executives about how evil and awful one side was than I did about HPI. It was depressing that I had to be bombarded at work constantly.
