AlgoExpert Ease of Use

Everyone has different workspace preferences, but you can take a look at the AlgoExpert coding interface/workspace here. Some users report that the interface/workspace feels a little busy/too much going on. Others find it easy to navigate once you understand where everything is. 

When browsing through the library of coding questions, you can filter by difficulty (e.g., easy, medium, hard), category (e.g., arrays, binary trees, graphs, heaps), or sort them randomly so you never know what to expect. You can “star” questions if you want to bookmark them, mark them as completed with a strikethrough, etc. 

Within the code editor, you can:

  • Change the light theme (light or dark mode)
  • Time yourself with the built-in stopwatch 
  • Change the layout (quad vs. tri layout)
  • Change the editor font size
  • Change the programming language
  • Change the syntax highlighting theme

When you click on a coding question, you’ll go through a simple process:

  1. See the coding interview question/prompt 
  2. You can open up a few hints via a dropdown if you need help getting started
  3. Write your solution in the code editor and run it
  4. You can toggle over to the tab “Our Solution(s)” to see AlgoExpert’s answer and then toggle over to the “Video Explanation” tab to see the code walkthrough

Overall, AlgoExpert is easy to use, but can feel a bit busy/overwhelming when you’re first getting started.

AlgoExpert Content Quality

One benefit of using paid learning resources is that you can usually expect a high level of quality. That’s certainly the case with AlgoExpert. You’ll enjoy well-produced, high-quality coding interview prep content. 1080p videos boast crystal-clear audio and are strategically divided into two parts to give you the most comprehensive explanations to questions.

Code walkthroughs show Clément Mihailescu writing out solutions on both a virtual whiteboard and code editor. They’re clear and easy to see, follow, and understand.

What Past AlgoExpert Customers Think

The AlgoExpert site has a page featuring reviews from past customers. Here are a few samples:

Nick, Rotational Engineer at Facebook:

“AlgoExpert succeeds in a key area that other similar platforms fail by putting an emphasis on explaining the thought-process of each question. I’m not the type who wants to try and memorize 500 questions in hopes that my interview questions are ones that I have seen before – I want to really understand the concepts and patterns that would help me solve ANY question. AlgoExpert and SystemsExpert do a superb job of providing in-depth explanations of the patterns and thought that you should use to arrive at the correct solution, no matter the algorithm or design problem. I put my time and trust in AlgoExpert and I now have a job at Facebook to show for it. Highly recommended!”

Alex, Software Engineer at Google:

“AlgoExpert was the backbone of my technical coding interview preparation. It allows you to efficiently work through the most common variations of problems asked by top-tier companies without having to spend hours ‘battling’ an algorithm only to come up with an inefficient or incorrect solution. There are a lot of resources available for repetition, but AlgoExpert differentiates its product by providing the ‘how’ and ‘why’ in clear and concise videos. Developing a deeper understanding of how to approach these problems is better than trying to memorize lines of code. I highly recommend AlgoExpert.”

Elana, Software Engineer at Bloomberg:

“The video explanations and detailed code examples on AlgoExpert have changed the way I approach coding problems. It has been an incredible asset during my career journey and I highly recommend it to anyone preparing for the job market.”

AlgoExpert buyer testimonials

You’re most likely to benefit from using AlgoExpert if you fit one of these categories:

  • Someone facing their first programming interview / hasn’t had one for a long time and needs to brush up
  • Software engineers who have less experience in data structures and algorithms and want to get up to speed with them
  • Possibly overwhelmed by the idea of tech interviews and doesn’t know what to expect; doesn’t know what to do to prepare
  • Enjoys video explanations and likes to see step-by-step solutions
  • Those who want to improve their problem-solving skills

AlgoExpert Review Final Thoughts: Is AlgoExpert Worth It?

AlgoExpert is a great option, but it isn’t the best one for everyone. If you’re looking for a community aspect where you can ask and answer questions about your code solutions, you might want to look elsewhere. This also isn’t for people just starting out on their coding journey.

In short, independent learners who enjoy detailed, tutorial-style video explanations will appreciate AlgoExpert. It’s great for someone with prior coding experience who’s ready to start job-hunting and wants to be interview-ready.
