Pros

Accepted pretty much anyone. Training was first few months.

Cons

Once you go through training you're pretty much just thrown into it which is stressful at first if you're someone who likes to be prepared for things. Lots of travel

Pros

None. Management will not support you. It is do as they say and meet their unspoken quota.

Cons

Poor line management and directors.
