Woven

Woven Teams

Woven is a human-powered technical assessment specializing in experienced developers. Instead of just automated scoring, 2 of Woven's certified engineers evaluate candidate work. This enables unique scenario types for more-senior work like Github Pull Request Review and Systems Design. This creates a better candidate experience for in-demand Senior Engineers, which cuts drop-off in half versus automated assessments (40% vs 15%). And because these more-senior scenarios are more real-world, they deliver better signal on who will pass technical screens and final round interviews. This saves engineering time. Woven customers often replace take-home projects and shorten interview steps to move faster. NEW Detect ChatGPT Cheating: Woven is now the only technical assessment with remote proctoring on all plans. Try using ChatGPT on other platforms to see how their detection holds up!

Edabit

When learning to code, most people get stuck on the "bridge" between memorizing syntax and understanding the logic that makes it all work. We believe the most effective way to learn a programming language is to break the process into three phases: 1. Memorize syntax 2. Solve problems 3. Make stuff Most beginners jump from memorizing syntax directly into making stuff (or trying) without fully understanding how syntax is used to solve problems. In other words, they haven't learned how to think like a programmer, yet they're trying to solve problems like a programmer. Edabit was created to bridge this gap, while also making the process fun and addictive.

The programming interview is a winnable game. I'll show you the tricks to quickly solve problems you've never seen before. I'll teach you the right way of thinking for breaking down tricky algorithmic coding interview questions you've never seen before. No prior computer science training is necessary — I'll get you up to speed quickly, skipping all the overly academic stuff. Big O notation is the language we use for talking about how long an algorithm takes to run. It's how we compare the efficiency of different approaches to a problem. It's like math except it's an awesome, not-boring kind of math where you get to wave your hands through the details and just focus on what's basically happening. With big O notation, we express the runtime in terms of—brace yourself—how quickly it grows relative to the input, as the input gets arbitrarily large.
