It's unfortunate, but all the companies are doing this. Here's what a Google lead said in a tweet: > Hello, my name is Tim. I'm a lead at Google with over 30 years coding experience and I need to look up how to get length of a python string. DHH: > Hello, my name is David. I would fail to write bubble sort on a whiteboard. I look code up on the internet all the time. I don't do riddles. Max Howell: > Google: 90% of o…

More, many of the interesting proofs that folks know took a long time to develop. Sure, you could probably throw some up on the board and speak to it. No, you are not likely to be able to derive one. And, I highly doubt that without practice would you be able to even get it on the board correctly.
Which brings up a major point. Discuss more in code reviews. Don't polish them trying to make them perfect. Make them part of your conversation with your peers where you are. I personally even feel recommend to throw up straw men sometimes. It can be odd throwing up a review for the team to see an idea on code you don't intend to push, but it can also be a good conversation. And someone else may be able to take that idea and make it awesome.
Which is ultimately what I want from a coding interview. If you have to handwave over parts, fine. Just be up front about it and hide it behind a function call. I may ask you to drill in on that function, but the key is to get valid code. Not necessarily complete code. (Obviously, YMMV.)

Your explanations were excellent. I especially liked the way you introduced hash tables using a simple array where the indices had special meaning. The diagrams are clear and helpful. Only nitpick: not sure how somebody who is supposed to learn what an array is by reading this is supposed to already know the meaning of Big O notation. So maybe a little intro to Big O complexity somewhere in there would help as well.

Nice site but your questions are pretty run of the mill these days. Would be nice to see some new, original questions :-). Also an option to schedule some mock interviews would be great!
For mock interviews, definitely check out:

Earlier quoted context omitted.
You've got a cool site and I appreciate all the hard work creating high quality content (I've looked at the free questions and considered subscribing a few times in the past). I think your business model/pricing could use work. Unless I'm mistaken and things are going well .. in that case, I'll withdraw to my cave :-p My suggestion would be to have a slightly cheaper tier (probably no more than a hundred bucks). This…
Thanks for the note. Definitely a great point. Not sure yet how we tier out our product, but tiered pricing is definitely the state of the art. We've been working on some /tech/ to enable tiered pricing in the meantime. The Site's all custom, and so far there's no notion of a "product" yet...just "paid" and "unpaid." Share your question re: where's Kaplan on this stuff!
As the guy above was suggesting, that data science site does personalized feedback and that justifies the high price. Otherwise, the way it is now, it feels like it should be priced similarly to CTCI.
i actually have began to enjoy places that use these types of things for interview questions. it's a good way for me to know that i don't want to work there. i once interviewed at a prominent company focusing on a certain language. they specifically stated in their job application that they just wanted motivated, enthusiastic, and smart people and that they didn't care if you knew said language. i sent them my resume…

That's true, but this kind of interview questions will always be asked even for so called BAT in china.
