Above average salary and huge incentives
Pros: > Huge huge incentives. Base salary is above average already and if you can perform then your incentives can be higher than the salary itself. > Free lunch and breakfast (huge savings) > Free shuttle (another huge savings) > Friendly leaders | Cons: > The only downside is the sales targets that are hard to reach. Every month, there's a chance you'll get removed if you don't produce or perform
