It was a disappointment because I expected better from a YC company's process. Of course, I can't really blame Zapier for passing, as I'm sure there are a great deal of applicants and, since I never talked to anyone, I can't know whether we'd be a good match, technically or culturally. For example, many remote companies, especially those that are primarily staffed with offshore employees, are just trying to pinch pennies and paper over it by talking about the hipness and uniqueness of their remote workforce.
Zapier is a custom Q&A intake application [or, at least the applications I filled out were], so it's irksome to write real answers to those Qs and get nothing back. I'd much rather write an HN post where I can wear my rightly-deserved downvotes and critiques with pride -- then I at least get something for the effort! ;)
So, note well, potential applicants: "would love to talk" seems to mean "would love to have you languish in our HR system after you've taken the time to fill out our bespoke long-form questionnaire". Like I said above, usually it's hard to fault companies too heavily for this, but when the CTO is making a personal appeal on HN, I feel like a counterpoint is warranted.
Hiring in general seems to go very slowly these days. I don't know if everyone is flooded with fake resumes from "bootcamp grads" or what now, but 5 years ago or so, you could normally expect to hear back within a few days if someone was interested. It's a different ball game now. In the last couple weeks I've gotten two replies to applications I sent in around Christmas time -- one "an invitation to interview" from a well-known company (which I ignored), and one a message from another company that they'd closed out my application in their HR platform.
