@jc4p I put in the cover letter for every job my bot applies for + I send an additional page customized to the job poster, here is an example: http://job-diana.herokuapp.com/users/jobs/07c5807d0d927dcd09...
And here is the automated cover letter:
Dear Hiring Manager,
Hello, my name is Juan Ortiz. Nice to meet you!
I actually wrote a bot to automatically apply to your job because it looks like it's a #{fit} fit for my skills - my matching algorithm actually said there is #{percent}% chance you'd be interested in interviewing me.
You can check out the match profile I created for your job posting here: #{url_for_analysis} I'd really love the opportunity to interview at #{company_name} for the open #{job_title} position.
Thanks again. You can reach me at #{phone_number} if you'd like to chat.
P.S. if you're interested in how my bot is actually handling applications for me, you can check out the source code that applied on github: #{link_to_github}.
