Ah, you're talking about going through our regular process and looking for a job? In that case, we try to make it clear that what you're doing is applying for a job (and we require an account creation at the beginning of the proce

Re the % scores, they're currently set based on the people we had test the quiz yesterday. May well not have been a representative group! We'll reset them later today.

The truth is that there's just a lot less demand for remote engineers, and among companies that do hire remote, it's usually for very specialized roles. (There are obviously exceptions.) Looking at our stats, about 5% of the compa

Hmm. We included those issues, because we see a lot of programmers get stuck on exactly those two bugs! (In all sorts of languages, not just Python). I guess maybe that's the definition of a gotcha -- a thing that a lot of programmers

Just added anchors to the expressions. Thanks for pointing this out!

Hmm. Just checked again. Two of the expressions match neither word, one matches both, and one matches only one. EDIT: I see. The confusion is over partial match vs whole match. I thought whole matches were standard when talking about regu

Well, the questions get into other things too.(Character encoding, timing attacks, graph algorithms.) Writing a good single-paragraph description of iterative deepening depth-first search was a challenge!

Good point. I think that objects are passed by reference in a high enough % of language in common use (PHP and C++ are the two exceptions I can think of) that this is a fair question. But if enough people think it's bad, we'll r

We talked a bunch about this. Python and JS are the two most common languages we see on our site, and Python has slightly more compact syntax, which works well in the questions. The idea, however, was not to require any python-specific know

We've been using a quiz as part of our hiring process (at Triplebyte) for the last two years. However, a lot of people do our quiz for fun. So we decided to create a version optimized for this (and hopefully a little education). The pr

So... I showed up for this interview without realizing it was going to be on video! Can you see the terrified look in my eye? But Craig did a great job and got me through it. Thanks Craig!

An interesting point is that about half the companies we work with want their front-end developers to show full-stack understanding and strong CS (the argument is usually that they want to hold the entire team to the same standard so that p

Yeah. Trial employment better be paid! :) Even with pay, unfortunately, folks with an existing job often can't take the time off. And when people have the option between one company making an offer and another with a trial period, they

This is all just really hard (and counterintuitive). We've tried take-home projects, with and without asking the engineer to make changes live. This is actually very controversial (a lot of engineer are, reasonably, against the time co

Interviews absolutely should be grounded in trying to predict how a candidate would do on a job. That's the whole ballgame. The question is how to best do that. First, you need to run a repeatable process (my previews comment). Second,

We actually put a bunch of effort into consistency/repeatability checks. Every interview is recorded (video), and we re-watch and re-grade a percentage of them to measure the consistency. A long-term experiment we're running is co

We work less well with very specialized positions. However, the approach of identifying strong general programmers, and then matching the ones who want to work on compilers with compiler jobs works surprisingly well (still often results in

Having designed the new IR in Google's V8 is a very strong signal. The problem is that it's vanishingly rare to encounter someone who did that. The much more common case is companies just giving strong preference to anyone who has

I'm sorry that the interview went poorly! I'm especially sorry about the lateness. I just pulled up our notes from your interview, and I was your interviewer! So that makes it especially bad :( I'm not an expert in all areas.

So, those are not (unfortunately!) the primary way that we match engineers with companies. It comes down to questions about how important it is that engineers are strong in academic CS (some organizations think very, others think it's

This differs substantially by company. Some companies have one general interview process, and handle team/role assignment after making offers (for some reason this is common at very large companies and very small companies). Other comp

I'm sorry you did not like our process! For what it's worth, we've tested a bunch of types of questions, and relatively easy questions answered quickly provide the highest accuracy / time ratio. We also cover a bunch of

I don't think the problem the author is highlighting here actually has very much to do with recruiters. The recruiting industry _is_ full of scamminess (spam to both engineers and companies, false-flag recruiters who claim to represent

The low resolution of the stereogram is interesting. If you look at a wall at an angle, you see large steps, rather than an angled surface. Looking into this, it's caused by the fact that the program limits pairs of constrained pixels
