Pros
Moxie could potentially be on the brink of something very exciting. The company has headed in a new direction in recent years, and has a chance to be a real innovator. Whether it'll succeed is hard to say.
Depending on your office and your team, your outlook on Moxie can change drastically. My team has an atmosphere of mutual respect, and generally good work/life balance. I'm sure folks on many other teams feel equally valued.
Our headquarters in California recently moved, and I hear those digs are pretty sweet.
Moxie is a small company, so if you don't like to feel like another cog in a massive machine, you might like it here.
Cons
I know from office chatter that not all teams have high morale.
The Bellevue and Austin offices are comfortable, but would certainly not qualify as visually appealing. There's plenty of desk space to go around, and a ping pong table that rarely gets used.
My biggest complaint about Moxie is its lack of company culture. I'm sure this is different in each office, and there are definitely a few people dedicated to making it happen; but overall, most attempts to "rally the troops" are met with eye rolls.
Overall, Moxie can feel like a comfortable but mediocre company. If you're interviewing for a job that's the next step in your career, it could be a great move. If you're moving laterally, it might lose its luster pretty quickly.
