I really liked the approach to beginner freelancers: a year ago I started my career in ui/ux and had a small portfolio, I was very surprised when I saw that I was immediately allowed to take the task, because before that I had never been chosen as a performer.
The pluses were very clear terms of reference and a decent level of pay, plus a deadline that allows me to do everything calmly, even if the main work overload
As for the minuses, I remember a couple of times there were no available jobs, but lately this has been fine.
I have been working with GetWork almost a year on a regular basis and I don't regret it.
