Sorta ironic, but remember that the point of an interview is to determine how well you'd do in the environment that's hiring you, not how good a developer you are. Because Google tends to reinvent the wheel for basically everything, algorithmic knowledge really does matter. Package management only matters within a few very specific subteams. If you're interviewing for a general SWE position, you could be Mark Zuckerburg and still not qualify for it.
FWIW, I find Facebook turning down Jan Koum in 2009 and then spending $19B to acquire his company even more ironic.
