What do you put in the 'wage desired'space when you heard the company was hiring but you do not know for what position?

The best answer to put is "any" that way it covers all the positions. I actually take up applications with my job, and when I see that I know that they are really serious about finding a job. A better suggestion is to write " any that I am qualified for". A welder would not be considered for a spray painters job. Wrong qualifications.
