It has taken me, on average, 6 months to find new work each time I do it and I send hundreds of resumes. So I think you are doing the right things. It just sucks. Sometimes you can get a lead from someone you know and that gets your foot in the door.

Remember, you are reviewing them as an employer too. If they have a shitty applicant experience, that should play into your decision process (easier said than done when you just want to make rent).

Feel free to message me if you would like resume or other search help.
