No, it's not. The question word usually needs to be in the focus, ie followed by the verb. Exceptions that come to my mind are miért (why) & hogyhogy (how come.) There might not be any other exceptions, tbh.
Markets are, generally, open air environments, so you are considered to be working on them, whereas you'd work in a bank. Also you travel on buses, trams, and trains, but in planes, due to the lack of headroom in the latter.
