Applied long ago but never heard from your team. If someone spends time writing a letter to join your team other than just attaching a resume, it would be nice to let the person know if you are interested or not.
Sorry this has happened, that's not good at all. I know that a lot of effort goes into getting in touch with us (or anyone else). There was a time when I was personally handling all the hiring, and I struggled to get back to everyone on top of everything else I was doing. We have a much better hiring process now and we've committed to responding to every email. Sorry again that you had a bad experience here.
Sorry about that awful experience we caused there. We definitely had a period where we simply struggled to respond to everyone. We honestly get about 100 emails from this HN listing. When we were just a few people, it was hard to keep on top of. It's a poor excuse, and we're fixing it now (we genuinely get back to everyone now). We didn't handle this well for quite some time, though.
Use resumator or one of the other cheap apps for handling this. For most people a canned response is absolutely fine, it's the no-response that ticks people off.
We do make sure to respond (and provide feedback if asked) to everyone who applies. The issue that we're working on is our response usually comes 2-3 weeks after the initial submission.
