https://thehustle.co/the-secret-google-interview-that-landed-me-a-job<p>I remember finding a really cool one all over network requests at one time but can't remember the company. What are other great hidden interview processes?
Oh... I thought you talk about real hidden interview questions. Like the ones they use to figure out how you got the recommendation letter to this job (i.e. if it wasn't one of their faction who they must be careful about). Or when you get a referral at a competitor and in the interview they try to get your insider info without making you an offer (i.e. "tell me about the last interesting project you worked on"). Or when they try to figure out in your first tasks after hiring how far they can let you in to the actual decision making process without shocking you. Or when in the interview there are different factions present and each tries to see how much they can pull you to their side.
The repl.it jobs page is literally just a shell, and you have to figure out how to apply:<p><a href="https://repl.it/site/jobs" rel="nofollow">https://repl.it/site/jobs</a>
I feel like the pattern of "solve this puzzle, get an interview" has fallen out of fashion in the past few years.<p>In 2012 I got an interview at facebook by solving a puzzle that involved adding weights to a recursive arrangement of levers on top of levers. I remember both having a lot of fun with the puzzle and knowing that I would have never landed the interview any other way because I was coming from a non-traditional background and still relatively junior.<p>I think Google's foobar came out a few years later. I had some fun with them and got through the first rounds, but by that point I already had a job and never got around to finishing it.<p>I also remember doing some fun puzzles on codeeval, hoping their business model of linking people to companies would gain some steam, but the companies they signed up never seemed to be very interesting.<p>Is leetcode essentially the new codeeval?
Bandcamp typically has a fun application process.<p><a href="https://bandcamp.com/jobs" rel="nofollow">https://bandcamp.com/jobs</a>
<a href="https://leetcode.com/" rel="nofollow">https://leetcode.com/</a> is pretty popular and has lots of actual questions. However, Google actively bans any question that ends up there.
I just signed up for <a href="https://dailycodingproblems.com" rel="nofollow">https://dailycodingproblems.com</a>, a daily email of company interview problems. I can't speak to the veracity of the claims that the problems are from actual interviews, but I have no reason to doubt their authenticity. The premium version shares the answers, too. I like it so far.
I tried to design one of those for my company. We've typically just hired someone through my HN post about it recently, so I think it's working, but I'd still really like to get some feedbacks on it. I am very concerned about getting it right, having been through the shitty side of many interview processes.<p>omnistream-dot-co/job-opportunities/
The Curbside challenge was pretty fun. It may be the one you’re thinking of, lots of API calls to get the key.<p><a href="https://challenge.curbside.com/" rel="nofollow">https://challenge.curbside.com/</a>
Many tech companies add a link to their careers page in browser consoles. I'm not sure if that's "secret" or "cool" enough. (Facebook puts in a warning to prevent "XSS" attacks.)
Bandcamp has a fun puzzle on their jobs page: <a href="https://bandcamp.com/jobs" rel="nofollow">https://bandcamp.com/jobs</a><p>“To apply, gather the crumbs (starting with your cookies).”
i still remember SWIM googling for hours trying to force google foobar to pop up. when it eventually did, most of the answers were on github and it got me an interview.
Red Balloon Security 'hidden interview' process was pretty interesting, and fun! Too bad I wasn't good enough to go past a couple of stages, but to me it was the epitome example of your question.
