Pros
The benefits were incredible while I was there and they are what kept me going for as long as I did. Unlimited PTO, free lunches, and quarterly bonuses were all fantastic and appreciated. Working from home was especially nice.
Cons
I worked at 90octane for several years and it was a much different place than when I left. As I saw another review mention, it has basically become a mini-Faction (a Denver agency which went out of business). I saw cliques forming left and right and the general atmosphere was much less friendly/collegial than it was when I first started. As the company grew, I felt like certain departments were over-hiring, while other departments were neglected. That causes great work-life balances for some and extremely imbalanced lives for others. I think those in Director positions make extremely comfortable, generous salaries while those in lower positions are paid less than market average.
