The training was pathetic. Imagine you start a new job and your only training was a textbook, a couple of emails and some irregular feedback/coaching.
Add in getting yelled and screamed at for making one mistake and having to work well overtime just because you forgot a full stop.
The colleagues were average and weren't always supportive/caring. I don't enjoy rolling into work with a smile and saying hi to everyone and not getting a single response. Even if you are busy, just quickly say hello.
Finally? Working from home. I felt so isolated and like I had no personal space at all.
