Speaking of which, how do y'all get most of your hires? Referrals? I've emailed your careers email address for matasano, but I've not gotten a response. I'm not sure if it's because I'm not qualified or I got filtered somehow.
No, you should get a response and, if you're interested, a phone call from us, no matter what. Our process is pretty much resume-blind. So if you didn't get a response, you fell through the cracks somehow (actual humans read all those mails, we get a lot of them, and we have spam filters).
You can shoot me an email and I can figure out when this happened and maybe, if it's helpful for you to know, give you an idea what we did wrong on our side. Obviously, if you're still interested, we're happy to talk to you.
It's funny, one of the things I tell every person I talk to in our first-call process is "we won't go dark on you if we think it's not going to work out; we'll tell you ASAP --- but I don't promise not to go dark on you by accident". Everyone in our company is billable, which is good, but we're always hammered with stuff.
