I don't expect interviews. But I also don't want to spend 20 hours working before getting a "Unfortunately we've decided not to move forward" message.
As a thumb rule, I'm happy to put 4x more effort than the company. If they interview me for 1 hour, I spend 4 hours doing the take-home. Anything more feels like exploitation.
As a general rule of thumb, random series A startups are in much lower demand for top-tier talent than top-tier talent is in demand for these companies. That would mean that the good engineers should set the rules of engagement, and that any startup that thinks they set the rules is attracting worse talent.
Well, unless Qdrant writes a post complaining about the quality of their applicants, I don't see where the issue is.
Also, not all companies try to maximize for "top tier developer", it seems they are maximizing for "top motivated developer", which does not seem stupid either.
It sounds like they are instead maximizing for "free integrations," which seems to be a fine way to get neither free integrations nor high-quality candidates.
All the ivy league graduate leetcode farmers I know are actually the ones who would do the grunt work of developing database integrations for free if they believed a decent salary at a prestigious job might be waiting over the hill.
The people I have met with the lowest tolerance for this stuff are the ones who actually produce the most impactful work. Partly because they don't do work that has no impact on their lives.
Edit: Obviously, they can do whatever they want, but that doesn't mean that it's a good sign from outside.
"We receive a lot of applications" can be also a marketing speech and it could also mean they are flooded by spam requests from all over the world they can't filter out.
