The sense that I make a difference.
They are just like everyone else. No false pretenses.
People are happy to be here, and are dedicated to the mission.
We work together. We help each other out. At any time someone is willing to drop other things to support someone else.
Case study and the time spent to ensure I would be a good fit, and that I knew many of my coworkers prior to joining the team.
Being able to work where I want, and to have unlimited paid time off. This allows me to be an adult, and take care of things, and even work in other locations in order to keep a good work/life balance.
