What people say about our courses

Arijeet

Software Engineer

Just completed the “Grokking the system design interview”. It's amazing and super informative. Have come across very few courses that are as good as this!

Ashley Pean

Software Engineer

Check out Grokking the Coding Interview. Instead of trying out random Algos, they break down the patterns you need to solve them. Helps immensely with retention!

Eric

Software Engineer

I've completed my first pass of "grokking the System Design Interview" and I can say this was an excellent use of money and time. I've grown as a developer and now know the secrets of how to build these really giant internet systems.

Simon Barker

Software Engineer

This is what I love about http://designgurus.io’s Grokking the coding interview course. They teach patterns rather than solutions.

Steven Zhang

Software Engineer

Just wanted to say thanks for your Grokking the system design interview resource (https://lnkd.in/g4Wii9r7) - it helped me immensely when I was interviewing from Tableau (very little system design exp) and helped me land 18 FAANG+ jobs!

Roger Cruz

The world gets better inch by inch when you help someone else. If you haven't tried Grokking The Coding Interview, check it out, it's a great resource!
