at least one third if not half of the job applications i have come across have a required form field for expected compensation. initially i just wrote 0 or something obviously bogus, but i got concerned that this was used as a filter. so now i am not sure what to do. for european companies it is probably ok to just write something as they are unlikely to have a much higher range anyways. it really helps though if they actually post their range.
