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

Fifteen-Day Preparation Strategy – Get prepped with all the necessary concepts in just 15 days.

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

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

Trust me, this guide focuses on the 20% of topics that are asked in 80% of system design interviews.

Once you fall for System Design and Actual Software Engineering, you get bored learning or revising DSA.

I’ve curated a list of handy LeetCode posts on System Design interviews from top companies like 𝗠𝗘𝗧𝗔, 𝗚𝗼𝗼𝗴𝗹𝗲, 𝗔𝗺𝗮𝘇𝗼𝗻, 𝗨𝗯𝗲𝗿, 𝗮𝗻𝗱 𝗠𝗶𝗰𝗿𝗼𝘀𝗼𝗳𝘁.

If anybody says System Design is overrated in software engineering ask them to give a few interviews for SDE/SDE2/SDE3 role.

They quickly realize that mastery of DSA alone won’t land the job at top PBCs.

DSA a day can keep interview rejections away.

Yes, practicing at least one question per day can help you crack any SDE interview.

You can pass System Design Interviews even if you’ve never designed distributed systems before.

If you have copied files between machines with drag-and-drop, you are halfway there. If you implemented clients or servers or have opened network connections, you’ve got this.
