There are no shortcuts with system design, if you want to truly “get” system design, you have to go wide and deep. This is a great resource.

What is the purpose of hiding your own name from the offer letter? If it is not yours then why to post it and lure people to blindly follow you on the name of “top list of dsa which helped me crack blah blah company “?

amazing list! but real talk... you gotta get the interview first 😭 I built OfferPilot to match students with roles they can actually land so all this prep doesn't go to waste. free at https://offerpilotai.com/u/dvdw7

Thank you so much, really useful. Congratulations Sameer Bhardwaj

So much better than hopping from blog to YouTube to random notes. Wish I had this list when I started prepping for system design rounds!

What I love about this list is it covers the topics that actually show up in interviews.

Fantastic resource list for anyone diving into system design. It’s rare to see everything so well organized in one place. Which of these topics do you think gives the highest ROI for interview prep caching, scaling, or data partitioning?
