> Can only imagine what this is doing to code quality...
Why would studying algorithms and data structures affect code quality? They would similarly be able to learn to write quality code once they're inside the company, no?

While that is not a negative skill to have, it is also not a skill that I'd list anywhere in the Top-25 of most valuable skills for productive developers.
They work against creating readable, understandable and debuggable code which is much more important in general than being able to solve algorithimical problems you'll almost never see in real life.
I've seen this first hand where some were brilliant at these problems but wrote the worst code imaginable. I would rather hire someone who can write clean and simple code and teach them how to solve these problems than the reverse.
Why? Teaching people to write readable code happens automatically during code reviews, teaching people how to think is a lot harder.
It's quite condescending and narrow-minded to say that solving algorithmic problems is thinking, but writing clean and simple code isn't.
Writing readable code is much more than just formatting code and using decent variable names. It's about simplifying your design just enough. Code reviews is not enough to teach someone this.
First off, no, writing good code in an interview wins you additional points. Second, why do you think candidates can (or will) continue doing that on the job? New employees aren't allowed free rein to check in code from day 1 at most places - trust has to be earned. And I don't think any decent company allows check-ins without review.
Why automatically ascribe bad faith to people who study for coding interviews? They went to all that trouble to get better at something, so they're obviously diligent and seek self-improvement.
> Senior talent doesn't have the time or energy to push back on all of a systematically incompetent person's code until it's good.
That sounds like a problem with the company's timelines or priorities. If senior talent is so strapped for time that they can't insist on decent designs upfront, then they likely can't hire the right people either. Because even that takes time and energy. Mentoring juniors is part of the job for senior engineers.
It’s more than a full time job to push back on all of a bad hire’s output, and people are accountable for their own projects as well. Things inevitably get to “fuck it, good enough.”
Why is "passion" so important? And what even is passion? For professionals in every other field, competence, ability to deliver results, and getting along with people, are what matter. Many pros are passionate, in the sense of loving their work, but passion isn't a prerequisite for being a pro.
Sounds like most jobs need dispassionate guns-for-hire who'll do excellent work, no matter how tedious, get paid, and go home. In other words: pros.
Also, it's two completely different skillsets! There's something very weird about interviewing for X but then demanding Y. I don't ask my primary care physician how good he is at surgery, then be like "he knows how to learn difficult tasks, so we're good".
Presumably the first time they learned computer science fundamentals it took them some time right? People usually go to college for several years to learn this stuff - or 6-month bootcamps for 40-60 hours/week. Subsequently of course it'll take less time to refresh their knowledge.

I'm not disagreeing here. I just think most companies that use this interviewing style figure that X (easy to measure in 45-minute interviews) is a reasonable proxy for Y (much harder to measure). And Y (writing good code) is easier to train new employees to do as long as current employees maintain standards in code reviews.
Professional pride? Wanting to get better?
> Algorithms interviews are the only thing with an actual bearing on their future earnings.
Do they not want promotions or pay increases at their current jobs before leaving? Usually you have to do good quality work to get promoted.
Please read my original comment: https://news.ycombinator.com/item?id=20727948. People who lack these skills can learn after getting hired. Any software company worth working at has a code review and design review process.
