Does the job they're interviewing involve finding the longest paths on weighted bipartite graphs? Or is this just non-recursive Towers of Hanoi pretending to be a realistic work sample?
No, the position most definitely had absolutely nothing to do with longest path or combinatorial optimization.
Anyway, my larger point is that what I've been seeing interviewing is that these tests are becoming much more common at US startups without companies removing/reducing the rest of their technical evaluation process, nor really structuring the problems to be a good signal.
In an ideal world where companies do take home tests right, I think its a great solution. But what I've been seeing more often than not doesn't support that, making it hard to support.
I'm really curious what you've been seeing at Starfighter. Are partnering companies still going on to do a full technical interview? Or does Starfighter largely replace their normal technical evaluation?
Ignoring the fun of the challenges themselves (which probably isn't entirely fair), the latter makes it very compelling for a candidate. The former does not.
Most of our partners have a somewhat abbreviated interview for our candidates, but everyone (as far as I know) still techs our candidates out.
I'm actually fine with that! We make no pretense of having designed a screening process that is appropriate for every job. What I'm less fine with is the fact that the norm, even for abbreviated tech-outs, is 7-8 hours of on-site whiteboard interview.
