I would stay awaqy from Boss. A friend I know recently interviewed there and said their office ( inside the Gelber group) was a complete sh*thole...comparable to a bad college fraternity house with couches that looked lilke they were pee stained. I think they trade most products during European hours between midnight and 9am. I have a lot a respect for my friend and he said the manager of the group ( of Asian descent..I cannot remember his name) was a complete tool, clueless, very young and seemed in over his head. They have not been around very long so I would be hesitant to put all your marbles in such an unestablished group. That being said, Gelber group ( the parent) is a very respectable firm and Boss sounds like it is simply a small prop group that rents some space and clears under the Gelber name.
