Recently, we wrote about coding courses offered by CodeSignal Learn, an interactive AI-native learning platform that emphasizes hands-on learning to master new skills by practicing. You get instant feedback on your answers, as well as hints, summaries, and answers to your own questions. And coding isn’t the only field on offer at CodeSignal Learn: other subjects include Data Science, Communication and Leadership, AI, and Machine Learning. More good news is that CodeSignal Learn also offers many certificate courses and learning paths in personal development, business, and management fields. And if you’re preparing for a job interview, CodeSignal has you covered with nearly 50 learning paths in topics from Fundamental Coding in Python to Advanced topics for Senior Engineers in C++ or C#.
What is a learning path? Simply put, it’s a collection of several courses on a specific topic, leading to in-depth knowledge. You don’t have to complete the whole learning path to get a certificate. Individual courses each have their own certificate.
CodeSignal has been involved in the technical assessment business for several years, providing skills assessments to companies and individuals. In 2024, CodeSignal launched CodeSignal Learn to address skills gaps, and appeared in Time’s Top EdTech Companies of 2024 list. Starting with technical topics, skills now include leadership, public speaking, and negotiation.
The platform runs on a freemium model. You don’t need to pay to use most features, but interactions are limited in the free version. If you find yourself wanting more AI help (or want to submit the exercises more frequently), I recommend the premium subscription. You can upgrade for a month at a time, or take out an annual subscription for 50% less than paying monthly.
I’ve started several learning paths, and the gamification aspect makes it fun. Cosmo is a cute AI mentor who offers feedback on your answers and is always willing to create a video, summarize the lesson, or answer questions. There’s a Duolingo-style daily streak counter, and you can earn streak freezes for occasional days off. So far, I’ve earned a couple of free certificates and am looking forward to more!
