I've done some mass-applying with things like AngelList, but generally I like to take the time to research a company, write a thoughtful cover letter, etc. It'd be hard to do that 100 times a day, especially if I'm going to do anything else with my day. Do you think quantity is more important than quality?
I don't think you can judge quality until you're actually employed. The best looking jobs on the surface turned out to be some of the worst jobs I've ever worked. There's a lot of similarities between dating and finding a job, heh.
For you, no. Sad truth is a lot of companies are biased against interviewing bootcamp graduates because it's a total crapshoot. Anything you can do to make your resume or application prove your not brain-dead is really going to help.
If you're applying to 100 jobs a day, you have no idea what you want to do. There may be 100 'developer' jobs to apply to, but a JavaScript Developer and Java Developer Position are drastically different positions. Pick one and get good at it. You might not be able to apply to 100 jobs a day this way, but I guarantee you will get more interviews this way. Quality, not quantity.
