Vantaggi
ADP pays decently on industry standard and offers benefits to appreciate. Coworkers are intelligent and driven. There are a lot of opportunities to move to other teams/positions, you just have to endure the first year. Incentives are great if you can attain them - think of the constant dangling carrot effect.
Svantaggi
At ADP, you will experience the generic corporate culture. Not really a social environment, or what you can call a "fun culture." It's hard to find excitement every morning coming to work. Expect constant micromanagement and metrics. Metrics drive all conversations and perceptions of you as an employee and unfortunately, these metrics aren't the ones that actually matter and help move you towards you achieving your quotas. On a daily basis, you will receive messaging from corporate and your manager on how you need to do more activity (even when you're at your quota for your month). You're constantly compared to your colleagues. These are all probably a small attribution and explanation of the constant turnover you see here.
