who could have seen this coming, other than everyone who told the homebrew tree inverter guy this was a bad idea they absolutely shouldn’t do
the homebrew tree inverter guy
I knew he did homebrew, why “tree inverter” though?
Dude couldn’t invert a binary tree in an interview and so couldn’t get a job, allegedly.
No one could figure out what inverting a binary tree actually means. Like maybe swapping left and right or something?
In which case the best way to invert a binary tree of course being:
struct Node { private: Node *leftish = nullptr, *rightish = nullptr; public: static bool inverted; // I hope no one ever needs two trees... // O(1) tree invert operation! void Invert() { inverted = !inverted; } Node &left() { return inverted ? *rightish : *leftish; } Node &right() { return inverted ? *leftish : *rightish} }; bool Node::inverted = false;Don’t change the tree. Change your perception of the tree.
idly, first time I’ve seen lemmy do any sensible render with a textblock, which retro-informs a lot about the choices for text handling (which we’ve wondered bout in the other thread)
A whiteboard is just a glorified chalkboard, and I got sick of being asked to prove I understood how to use and manipulate one of the most complex systems ever invented by man by basically rubbing a soft rock against a hard rock.
I’m now in favor of puzzle interview questions, just so this guy gets asked them
His complaint seriously backfired here, because it makes working on a chalkboard sound epic. The act of rubbing one rock against another becomes ascendance into the highest realms of thought? That’s fuckin’ alchemy, bro.
If computers are “we taught sand to do math” then this is “we learned to read and count from people who were rubbing stones together.” Screw fire, we learned shakespeare from rock friction. Awesome.
yeah, I’m thinking there were a few more problems than not being able to invert a binary tree
Or possibly the interviewers simply liked the other candidate better. Maybe the other candidates blew them away, maybe there was a hiring freeze during the search, maybe it was vibes. If someone’s from an underrepresented group in the profession and you have a consistent pattern of rejection at a certain stage, you can maybe draw some conclusions, but “I’m deserving so I’ll get the job” isn’t how hiring works.
That being said the guy is clearly a massive cock & I’m sure that came through.
I will quote the entirety of Max’s website here:
MAX HOWELL is a legendary open source developer. Creator of Homebrew, used by tens of millions of developer around the world. Founder of tea protocol a decentralized technology protocol that enables open source developers to be rewarded for their software contributions for the benefit of all humanity. He is known for his careful approach to software development that results in delightful products that solve their niches perfectly.
what a fucking metric. I’m a lot closer to being a legendary open source developer than I thought.
also I found his TED talk on AGI while I was looking that up:
Max Howell draws back the curtain on the reality that artificial super intelligence will be here sooner than we think, and shares his approach to thinking about how it might impact our future. Max Howell has a master’s degree in chemistry, but after a year in the profession, abandoned it upon realizing chemistry is “super boring”. He began exploring open source coding. After working at Last.fm, then TweetDeck, Howell created Homebrew, an open source software manager that is today used by about 50 million people. He also authored a tweet about the interview process in the software industry that has been viewed more than 3 million times. Last year, he and his wife started a mobile app development company in Savannah.

boo
he authored a tweet
I will quote the entirety of Max’s website here:
Wait, the dude wrote that about himself? Jesus fucking christ, I wouldn’t hire him for anything just based on that. “Hello, I am Max Howell and I have a LEGENDARILY giant dick that pleases multitudes.” Get the Howell outta here.
I mean sure? Swapping the pointers recursively is also fine. It’s a question meant to see if the interviewee can talk about data structures or code, not to come up with a perfectly optimal working solution. Having a lengthy discussion about what “inversion” of a binary tree even means would even be totally fine imo.
I’ve interviewed a fair number of candidates and I ask them a very simple question with a bunch of edge cases and grade them based on how they talk about it, not the final solution.
I get the feeling that Max got frustrated and wasn’t able to coherently speak about the problem, or the interviewer was dumb as rocks. I think both are equally likely.
Oh yeah I’ve had the misfortune of giving hundreds of interviews – mostly programming interviews, but also talking interviews which I consider vastly superior. As well as being on the receiving end of a few.
I’ve definitely had people do poorly under pressure before. This can be over-complicating the problem, clamming up (surprisingly common), or simply getting too worked up by the interview setting. I hate that because I often think they could have met my rubric in a more relaxed environment.
I’ve also been on the receiving end of bad interviewers. Don’t get me started on HP asking me to implement offsetof in C++… n.b. implementing offsetof in C++ w/o undefined behavior is impossible it has to be a compiler builtin.
here’s a hacker news thread that talks about it. to be fair to Max, the question (and the Google-style interview in general) is absolute bullshit. to be entirely unfair to Max, he seems like a fucking asshole and his recent projects have been crowd-sourced consent violations.
I was one the people dealing with this project spamming the Ghost project. This second way of crap triggered by the project doesn’t make my any happier.
