ONLY A GITHUB PROFILE
It seems pretty clear that the bootcamps told you we really care about your github profile, and that sometimes gets interpreted as "to the exclusion of everything else".
APPARENTLY BORN SIX MONTHS AGO
Related to the over-emphasis on github profiles is the exclusion of anything not-code related. I get that code bootcamps attract lots of folks who maybe got a political science degree or spent the last three years in real estate. Tell me that. I'd love to see what you've been up to, we're looking to hire you, not your ability to code. I hope these institutions aren't making folks feel like their past isn't valuable because it didn't involve Rails.
ALSO THE GITHUB PROFILE IS BORING
The profiles tend to have some code camp rails homework in them. It's hard to go from learning to code to having a github profile that's impressive in a short period of time (Hell, I've been working for well over a decade and my github profile isn't impressive!).. That said, if you do want me to care about your github profile I'd rather see signs of enthusiasm in the form of personal gists or projects or thoughtful bug reports or feature tickets on other projects.
DISGUISES THE CODE BOOTCAMP AFFILIATION
Seems like the elephant in the room on these things is where you've been learning to code and how you found us. Many of the resumes seem to avoid being transparent about this. I wanna know which bootcamp you did, what got you interested, and how it went.
THEY TOLD YOU TO EMAIL US
It's clear that we're on a list and plenty of candidates email us without knowing (or maybe caring) about what we do. That's a non-starter. Frankly, I doubt that the people who even put us on the list of shops to mail looked any closer than a crunch-base profile or Who's Hiring post on HN.
RAILS
The resumes I'm seeing clearly come from a bootcamp that emphasizes Rails and JS/HTML. That's great, but we're not a rails shop and the candidate is brand spanking new to this. It's probably better that you continue your investment in Rails before doing a wholesale dive into another platform.
At any rate, I love that camps like this exist. I've long thought our industry needs really good trade education to supplement CS programs which are focused and affordable ways to launch folks who are interested into software development. I just think the packaging and presentation of folks coming out of these things could use some work.
