First, it is definitely standard process to tell him (if they didn't, that's a definite failure).
Again, remember you only have one side of the story here.
I like to try to gather facts before assuming things.
IE Ready, aim, fire, not fire, ready, aim.
Admittedly more difficult in this case (and certainly, i have no access to it)
Second i'm going to point out a few things:
Experience may translate into wisdom, it may not.
Plenty of companies promote people just because they last long enough. So 20 years experience managing may translate into a high level manager, it may not!
I hold a bunch of patents too on compilers and other things, it's not indicative of much in terms of skill, because almost anything is patentable.
Lastly, SRE is not an ordinary site maintenance position by any means. I"m not even sure where to begin to correct that.
I guess i'd start here:
https://landing.google.com/sre/interview/ben-treynor.html
Does this mean this person is under/overqualified/exactly right?
I literally have no idea.
I just don't think it's as obvious one way or the other.
"Well, that sounds like a dumb recruitment process."
Judging an entire recruitment process based on one side of a story from a person who's clearly upset about an interview, and even 3 sentences i wrote on hacker news, seems ... silly.
If you want to do it, okay.
But everyone in this entire thread seems to be making snap judgements without a lot of critical thinking.
That makes me believe a lot of people here have a ton of pre-existing biases they are projecting onto this in one direction or the other (and you are, of course, welcome to claim i fall into this category too!)
I almost didn't jump into this discussion because it seems so polarized and rash compared to a lot of others
I think i'm just going to leave it alone because it's not clear to me the discussion is going to get any more reasonable.
