So last month, I held a poll in our community to understand the experience level of our members and I have realized that most of you have 1+ years of experience, while a lot of you have over 3+ years.

Keeping this in mind, I’ve created a System Design Preparation Kit just for you.

It took me 2 years to build this guide while working as a software developer. I’ve divided it into 4 parts:

15-Day Preparation Strategy: You'll be prepped with all the necessary concepts in 15 days.

System Design Concepts: Everything you need to know about system design.

Cheatsheet: Quick revision material to brush up before the interview.

50 Solved Questions: Detailed answers with HLD diagrams, LLD code, and in-depth explanations.

Check out my System Design Preparation KIT here: https://topmate.io/rajat_gajbhiye/1446625

PS: To celebrate 150K followers on LinkedIn, Use code SD15 to get a 15% discount (Hurry, it’s only for the first few users)

I’m really excited to share this with you all.
