Pros
Technology is in-demand in the market and has a good business model. I came across plenty of smart, capable folks who genuinely wanted to help their coworkers and clients be successful. Coworkers are typically super friendly and I've made great connections along the way. Free lunches once a week, some snacks in the offices. Free beer/wine on tap. Definite work/life balance compared to other companies.
Cons
No opportunity for equity, so employees have no skin in the game, no loyalty to the company. This creates tension because we know who will get paid out when IAS gets sold again, and it won't be the employees who were forced to sell their equity to Vista. Toxic alcohol culture reinforced by the company since offices always have beer/wine on tap -- this is seen as a benefit by some. One may observe how normalized drinking is at IAS, in a very old-school kind of way where certain employees seem to consistently drink . IAS supports alcohol consumption more-so than employees being fit and active; I don't need you to buy me booze, AND it'd be great if you reallocated resources to facilitate employee health and wellness. Company isn't compensating employees based on their market value or performance, even if roles and responsibilities change. Bonus scoring arbitrary. For example, recent changes were made from the top down where bonuses were suddenly "recalibrated" including an arbitrary Vista score (A, B, C, D etc) resulting in lower bonuses across the board than ever before. This was POORLY communicated to employees. My manager discouraged me from fighting for a well-deserved raise. Too many managers, first time managers (this is a BIG ONE) and middlemen to leadership, so if you're a lower level employee or individual contributor even if you communicate a gap, things are unlikely to change. The rate of change is painfully slow. Constant change in leadership, folks coming and going. As an employee/IC, it may feel like you are expected to continually prove yourself to someone new who may not even be around to see through to or be invested in your successes. IAS is a pretty large company, and unfortunately even with the best intentions the CEO can only affect so much change in so much time. Current leadership for certain teams is still figuring out how to forge career paths within the company, so unless your goal is to become a manager there are no opportunities for advancement and won't be for some time, opportunity cost for employees leading to attrition. Poor and toxic leadership in some cases not only goes unnoticed, but may even get promoted (360 reviews anyone??). For example, I have been personally chastised by certain leadership in a very unprofessional way and was assured their boss would address (with seemingly no change or positive result). And hearing from multiple employees that HR complaints have already been submitted with no results further discouraged me from addressing.
