You write, we guide

AlgoCademy helps you translate ideas into code, guiding you step by step, thus making the whole learning experience more interactive than just following a video lesson and copying what is presented there.


Keep it clean and simple

We all hate red flags, don’t we? And choosing a bad variable name or overcomplicating the code is one of the most common mistakes in a job interview. That’s where our Code Quality Tests come to the rescue and shows you when your code won’t land you the job, even if it works.

Boost your problem solving skills

A picture is worth a thousand words. But a video offers you more than that. AlgoCademy’s video content doesn’t just hand you over the solution, it will get you in a thinking process adventure where you will easily develop your problem-solving skills. You'll be able to solve any problem you'll face during an interview

Senior Software Engineer at Facebook

"When I realized I had a problem with coding interviews even as an engineer and ex competitive programmer, it was out of control. I needed guidance immediately. AlgoCademy showed me what my coding was lacking right away, and I haven't failed a coding interview since —I would definitely recommend them."
