Vantaggi
Based around core values like authenticity, generosity, and empathy, the culture at Moz is fantastic. The people truly care about one another, and want each other to succeed. This is especially true of senior management. Salaries are competitive, benefits are really wonderful (vacation expense reimbursement and professional coaching, e.g.), and there's lots of room/encouragement to grow as an employee. Moz has also matured quite a lot over the last few years. It's exited what some call its "teenage years" and has become more efficient and effective as a result, despite some necessary speed bumps along the way. The recent acquisition of STAT Search Analytics is exciting -- that team and product will be a powerful addition to Moz.
Svantaggi
The last few years have brought a ton of change at Moz, including in strategy and senior leadership. It'd be a difficult place for those who aren't comfortable in an environment where strategic direction regularly shifts. In addition, all that change has often made it difficult for the company to function as a cohesive whole; quite a lot of time is spent revisiting planning and procedures. I do think that's a temporary issue, though, and it pales in comparison to the more positive aspects.
