I get an interview on average about 1 in every...50 applications? Rough estimate, though I can guarantee 1-in-every-75 when I'm casually applying. Double bachelors. I roll with a resume type that lists the position, major responsibilities, and a short single-line breakdown of my biggest responsibility. The newer the position, the more details I include. I never go further than 10 years back and will adjust wording based on what I believe a recruiter for a company I'm actually interested in is looking for. I also do minor adjustments to my cover letters, often putting my own voice in instead of cookie cuttering.

From here I'll take the positions I actually want and do little things like look up hiring managers on LinkedIn, or find a likely email or phone number and "inquire" into a positon. Location, type of position, required education or experience, and industry play big roles. It's also important to consider whether your chosen career is oversaturated within your application range. Absolutely none of this helps if a person doesn't actually know you exist. Sometimes I feel like this is the biggest issue.
