Vantaggi
Diverse culture, inclusivity, top-notch talent, universally recognized global brand, many opportunities to learn and expand your knowledge and skills. EY has a "door opening" brand, which is great for establishing immediate credibility. EY also has some seriously talented subject matter experts - If you can find them and have them mentor you, you can acquire years of knowledge in a very short time
Svantaggi
The knowledge management system is less than horrible, meaning we would spend inordinate amounts of time re-creating the wheel every time - So instead of focusing on driving intellectual creativity, we were tinkering with presentations and trying to contact people and sending blast messages in order to (hopefully) find something we can leverage. The organizational walls between the service lines promoted very bad behaviors, meaning partners and other leaders made (staffing and operational) decisions on pursuits as well as live engagements based on their individual or group incentives, often to the detriment of the larger objective (client delivery). Favoritism, empire building, backstabbing - Way too much of this happening at the partner level - Based on what I saw, I believe this was more a few rotten apples in the SC&O group rather than the larger firm, which was and I'm sure still is top-notch
