About Corey Quinn
Over the course of my career, I’ve worn many different hats in the tech world: systems administrator, systems engineer, director of technical operations, and director of DevOps, to name a few. Today, I’m a cloud economist at The Duckbill Group, the author of the weekly Last Week in AWS newsletter, and the host of two podcasts: Screaming in the Cloud and, you guessed it, AWS Morning Brief, which you’re about to listen to.

Corey: Welcome to AWS Morning Brief: Whiteboard Confessional. I’m Cloud Economist Corey Quinn. This weekly show exposes the semi-polite lie that is whiteboard architecture diagrams. You see, a child can draw a whiteboard architecture, but the real world is a mess. We discuss the hilariously bad decisions that make it into shipping products, the unfortunate hacks the real-world forces us to build, and that the best to call your staging environment is “theory”. Because invariably whatever you’ve built works in the theory, but not in production. Let’s get to it.
Sponsorships can be a lot of fun sometimes. ParkMyCloud asked, “Can we have one of our execs do a video webinar with you?” My response was, “Here’s a better idea. How about I talk to one of your customers instead, so you can pay to make fun of you.” And turns out, I’m super-convincing. So, that’s what’s happening. Join me and ParkMyCloud’s customer, Workfront, on July 23rd for a no-holds-barred discussion about how they’re optimizing AWS costs, and whatever other fights I manage to pick before ParkMyCloud realizes what’s going on and kills the feed.

Welcome. I am Cloud Economist Corey Quinn, and this is the AWS Morning Brief: Whiteboard Confessional; things that we see on whiteboards that we wish we could unsee. Today I want to talk about the worst whiteboard confessions of all time, and those invariably all tend to circle around what we ask candidates to do on a whiteboard during job interviews. There are a whole bunch of objections, problems, and other varieties of crappy opinions around whiteboarding as part of engineering job interviews, but they're all a part of the larger problem, which is that interviewing for engineering jobs fundamentally sucks. There are enough Medium articles on how trendy startups have cracked the interview to fill an S3 bucket. So, I'm going to take the contrarian position that all of these startups and all of these people who claim to have solved the problem, suck at it.
And these terrible questions fall into a few common failure modes, most of which I've seen when they were levied at me back in my engineering days, and I was exercising my core competency of getting rapidly ejected from other companies. So, I spent a lot of time doing job interviews, and I kept seeing some of the same things appear. And they're all, of course, are different. But let’s start with some of the patterns. The most obnoxious one by far is the open-ended question of how would you solve a given problem? And as you start answering the question, they're paying more attention than you would expect. Maybe someone's on their laptop, quote-unquote ‘taking notes’ an awful lot. And I can't ever prove it, but it feels an awful lot—based upon the question—like, thi
