I only ask because your personal account of 100+ jobs, at 5 mins per application, doesn't seem like the best approach to me. When I was jobseeking, I'd research every job description & company thoroughly first, and if it seemed like somewhere I'd want to work then I'd spend probably 20 minutes or so writing a cover letter that came across as personal.
I'm sure our experiences aren't apples-to-apples, but I definitely got a very high response rate from taking this approach.
As a fellow job seeker frustrated by the "Look at all these great tools for Employers to make Candidates jump through hoops" slant in SaaS, your contribution is quite welcome. I'll admit I have a Candidate Assist SaaS type program in mind as well, definitely different from yours in approach and execution, so feel very good about encouraging your success. Maybe even the scales a little!
Having something like an animated gif or screencast that walks through the process would be invaluable. It would also likely be good to have a privacy policy. I've been evaluating things like this and if I can figure out it isn't the right fit without jumping through the hoops or sharing personal information it would definitely be preferred.
I'm thinking search job with our tool - https://getbetterluck.com/ and apply with your tool.
I only mention it, as I discovered how to do it (and auto upload) only a few days ago...
