CodeSignal for Developers

What do you like best?

CodeSignal has a lot of coding problems that you can use to improve your general programming abilities or prepare for a coding interview. In addition, different types of problems and a nice built-in IDE motivates the learner. There is also a "Tournaments" section, where a short 10-minute tournament happens every 20 minutes with four random problems from the archive, which is very fun, especially when competing with friends.

What do you dislike?

There are really fewer things to dislike about CodeSignal, but one thing is very sad about it: it does not work well on mobile! Sometimes I want to accept friend requests or just look up a problem, but I always need to switch to "desktop version" in the browser to get it working. I hope it will be fixed soon.

What problems are you solving with the product? What benefits have you realized?

I challenged myself and tried to solve 80% of the interview preparation problems in a very short time. It was tough, but I managed it. It has got both classical problems and original problems from various companies' interviews to prepare well. The prompt also shows the time you spent on a problem, which is a cool feature that motivates you.
