Pros
Iris is a good place to work, especially for graduates to get sales experience (definitely more in the accountancy division than the SME division). There is good progression if you're prepared to fight for it, but they really make you fight for it - a lot of promotions come from people handing their notice in.
Cons
It's pretty dog eat dog (as in most sales jobs) - we have clear jurisdictions for our areas but if there are any debates over deals being in your area you can expect to fight to the death with the other person, rather than have your managers independently verify the account (at least not properly). A lot of promotions come from people handing their notice in. There's a growing frustration that graduates are exploited due to their lack of experience, rather than proactively promoting them based on their performance and skills they have developed. People shouldn't be driven to the point of leaving - we can easily get more money elsewhere!
