In my job, if I have to, say, determine whether a linked list has a cycle in it, then I’ll Google for “determine whether a linked list has a cycle in it”. Trying to figure something out from first principles so I can make myself seem smart is a waste of my employer’s time.

It's remarkable that it continues years after people started making these critiques and years after working developers have broadly agreed about it. Developers have too little ability to influence the way interviews work, especially at massive companies, but even at small ones.

A few months ago,
@HM_Krystan put together a Dropbox Paper document entitled "Our Job Ad if Krystan Had Written It" It was awesome work, and I really appreciate the willingness of engineers at@tildeio to try things like that, knowing that their ideas will get a real hearing. - 2 more replies

Google is fair game in our coding interviews. One candidate said it felt like cheating. I said no, it's like working. If you can just look up the answer, you get full marks. After all, knowing when you found the answer and how to apply it is a skill in itself.

And then you end up with codebases that reinvent the wheel badly because using the existing function would've been too easy.

Amen. It's also a major contributor to the dominant culture where engineers tend to self-evaluate based on mastery of minutiae rather than their progress towards solving the (great many!) problems current generations of software suffers from.

Perhaps in reaction to that, I do “Here is a specification of a simplified problem that you would actually be given on the job. You have Internet access, you can use any library.” It is definitely hard to tune the difficulty and define consistent metrics for how well it went.
