24 alternatives to Try out our real-world programming challenges

For CodeSprint 2, we decided to introduce Real World Problems: programming problems that our CodeSprint companies face in real life. Real World Problems are messy, complicated, and infinitely variable. They require API calls, use of an arbitrary number of libraries, and a file structure that contains more than a single file upload. In short: Our existing code checking architecture is mostly useless. So we're writing a new one. Please help us test it. beta.interviewstreet.com

CodeSprint 2 introduces Real World Problems, a new testing platform featuring programming challenges based on actual issues companies encounter in production. Unlike traditional coding problems, these challenges are… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    Hi HN, I have been making side projects since I was 14, and my team mate (this is his very first side project! Congrats!) designed and implemented the UI. Over time, people kept asking me how they could start coding and turn ideas into reality. So we had an idea. Coding is changing. With AI, the bottleneck is no longer writing every line by hand but knowing how to prompt effectively to reach a working outcome. Our objective is not to make people code better, or even learn to be a proficient software engineer, but just to keep it simple and start building. We want to remove fear and barriers…

    Hey HN, I'm Aline, founder of interviewing.io and one of the authors of Beyond Cracking the Coding Interview (the official sequel to CTCI). We just compiled every problem (and solution) in the book and made them available for free. There are ~230 problems in total. Some of them are classics like n-queens, but almost all are new and not found in the original CTCI. You can read through the problems and solutions, or you work them with our AI Interviewer, which is also free. I'd recommend doing AI Interviewer before you read the solutions, but you can do it in whichever order you like. (When…
