Pros
You learn a lot to take elsewhere and have some other company benefit from it.
Kontras
* hardcore sales - no time to build actual relationships with clients due to unrealistic goals * a lot of overtime * not just stressful (hey, which job isn't) but actually disstressing a lot of the time * cultural differences are not taken into account * elbow mentality * unfair commission payments once you resign * you have to be available pretty much 24/7 if you want to have your clients (and therefore your commission) properly covered and you also have to travel quite a bit yet no laptops or smartphones are provided - which should be standard these days * sustainability is not something that matters to management * if you read headlines like “The most psychologically abusive institution I've ever been part of” - believe it! it's true
