User reviews

Incorrect solutions and limited problems

Some solutions (for example, find the second largest value in a BTS) are clearly incorrect. The app also only offers a handful of pretty random problems for each section. Great concept but needs more work to be useful in any way.

Response from developer

Thank you for reporting this, we've fixed the problems you pointed out. In addition we have added a ton of new content, especially around system design. Hope you like it!

Great free stuff

Amazing stuff and it is free!!! No ads that I noticed so far either.

Response from developer

thank you!

Great Resource

So far so good. C is not my strong language but I can still follow along easily. The external links to stack overflow are great when the solution isn't clear.

Response from developer

Thank you so much, we've changed the language to python now. We've also added a ton of new system design content!

Free and to the point

It is free people! It may not be the language you know. I honestly don't even know what language it is, but it gives you the explanation, approach, and some code. You want it to be a review on a typical coding interview. With that, 5 stars. He or she wrote this deserved a recognition.

Response from developer

Thank you so much, we've also added a ton of new system design content!

C? Seriously?

Why would you choose one of the hardest languages to have people study in? Almost all top professionals in this field recommend learning interview problems in easy languages such as Python or Java. Port it to those languages then maybe people would want to use it. Good idea, but please take this advice. I do have to say it is a smooth app. Loads fast and smooth.
