Pros
The interior of the gallery is quite pleasant and two of my colleagues were as nice as they could be given the circumstances of our employment. If you can handle the pressure and will do whatever it takes you can make money through commission.
Cons
Completely unrealistic targets and a company culture of vicious dishonest sales tactics that attempt to peddle utterly worthless pieces of artwork to clients as "investments". I had the unfortunate experience of accidentally speaking to several old clients on the phone who had invested huge sums of their own money into artwork which they then found out to be worthless in the actual art market. This is not like a normal sales job, I felt that I was being forced to harass people and pressure into sales. The artists themselves are held into strict contracts and most of the work is reproductions of various similar works. There is also a flood of new work which further causes to decrease the value. If you are considering working here I would whole heartedly tell you not to.
