Hy my name is Murat, one of the co-founders of Codela. Almost every developer we know has an interview horror story. After interviewing more than 2.000 candidates for leading technology & finance companies we have figured out the underlying core reason - MISCOMMUNICATION! 😰 In most cases, both the candidate and the interviewer don't know how to prepare for the interviews. Candidates study inefficiently, focusing on inessentials. The interviewers prepare the trickiest questions expecting candidates to pull off the mission impossible hacking scene. We're trying to solve this problem by providing both sides a free platform. Think of it as 🌟 WIKIPEDIA-FOR-TECH-INTERVIEWS 🌟. As we grow our collective interviewing knowledge, things will only get better for us, the developers.

Some of the challenges are really cool! It's certainly a very useful (and also entertaining) resource for all engineers.
