Indepth Review of AlgoExpert

Now let’s delve deeper into the platform, so you can have a full picture of what to expect.

Who are the Guys Behind AlgoExpert?

As you can expect from a platform of this nature, AlgoExpert was created by a seasoned software engineer who’s been through the coding interview process multiple times.

Clément Mihailescu, the guy behind the platform, is a graduate of the University of Pennsylvania and has worked as a software engineer at both Google and Facebook.

The idea for AlgoExpert came to him after he landed an interview with Google. To prepare, he had to pour through multiple articles and text books and watch a myriad of YouTube videos.

Despite hours upon hours of practice, he was left feeling frustrated. He decided to create an organized interview preparation resource that would leave software engineers feeling adequately prepared and confident to tackle their interviews. He launched AlgoExpert in 2017.
