System Design used to scare me.

I remember preparing for my first few interviews, reading random blogs, watching hours of YouTube videos, and still feeling lost when someone asked me about CAP or caching strategies.

That’s when I realized…

System design isn’t about knowing everything. It’s about understanding the right things deeply.

Over time, I figured out that 80% of system design interview questions come from just 20% of concepts.

So, I created this guide:
Focused. Structured. Real-world backed.

Dear Software Developers, a gentle reminder to:

- Learn DSA before jumping into Frameworks
- Learn Core JavaScript before React/Vue/Angular
- Learn HTML & CSS before Tailwind or Bootstrap
- Learn OOP before Design Patterns
- Learn Version Control (Git) before CI/CD
- Learn Core Java before Spring Boot
- Learn HTTP & APIs before GraphQL
- Learn Database Fundamentals before ORMs
- Learn SQL before NoSQL

Everyone wants to jump into shiny tools & frameworks. But it's the basics that make you a better engineer.

Harsh Truth but True

During the Interviews: DSA, LLD, HLD, Java, Spring Boot, JavaScript, Kafka, SQL, etc.

Actual Job: using IF/ELSE

Still, we must continue to upskill because competition is growing, and in-depth knowledge is now in high demand.

I'm sharing resources that can help you build a solid understanding of the topics

I have researched lots of product-based companies like Amazon, Microsoft, Netflix, Zomato, Goldman Sachs, Paytm, J.P. Morgan, etc., for SDE-1, and 2 roles, and found that these 20 system design questions are almost asked in every interview, both at the fresher and experienced levels.

If you are a Software developer looking for a job right now:

For preparation check out this KIT: https://topmate.io/rajat_gajbhiye/1446625

1. DM 5 people per day on LinkedIn.
   Not 50. Just 5. Focus on people in roles or companies you're aiming for. Be respectful, short, and relevant.

2. Don’t say “Can you refer me?” — earn the referral.
   Send the job link + explain in 2 lines why you're a good fit. Make it easy for them to say yes.

3. Cold email hiring managers.
   Use LinkedIn + RocketReach. Subject: “Application for Backend Role – 3 YOE | Java + AWS” → That’s it. No essays.

4. Your resume headline should speak like a recruiter.
   e.g., “Software Engineer | 3 YOE | React + Node.js | ex-Zomato” — not “passionate coder and lifelong learner.”

5. Remove generic summaries.
   They don’t help. Instead, add a “Key Skills” or “Tech Stack” section with actual tools.

6. Apply even if you match 60–70% of the JD.
   Most job descriptions are wishlists. Stop disqualifying yourself.

7. Reapply to ghosted companies after 45–60 days.
   Yes, it works. Many ATS don’t block reapplicants unless you’re rejected post interviews.

8. One mock every week. Non-negotiable.
   System design or DSA, with a friend, mentor, or platform. Interview pressure is different from solo Leetcode.

9. Build one clean side project.
   Hosted. GitHub link. Loom/YouTube walkthrough. Make it easy for someone to see your skills in action.

10. Use reverse job search.
    Find employees at companies you love → see what skills they have → build a similar profile.

11. Track every job you apply to.
    Company, role, date, status, contact — use Notion, Excel, anything. This helps with follow-ups and reapps.

12. Write 2-3 lines about each company before interviews.
    Their product, tech stack, funding. It shows you care and lets you ask smarter questions.

13. Customize resumes for different roles.
    Same core, but tweak for frontend/backend/full-stack focus. Keywords matter in ATS.

14. Be active in 1 tech community.
    Don’t just lurk. Ask questions, help someone debug, post wins, visibility builds trust.

15. Follow 5 hiring managers or tech leads in your domain.
    Sometimes they post roles before HR does.

16. Post weekly on LinkedIn.
    Share your project progress, what you learned in a mock, or insights from a rejection. Be visible.

17. Use Job Boards smartly.
    AngelList (startup roles), Wellfound, Triplebyte, Otta, Hired — but always follow up directly.

18. Prep behavioral questions too.
    “Tell me about a challenge…” isn’t just filler. Most people fail here because they wing it.

19. If you’ve been laid off, say it clearly.
    There's no shame. Add “Open to Work” + a pinned post. People help when you're honest and specific.

Never bet against System Design

Trust me, if you do, you will never crack any interviews

The reason you’re struggling with 𝗦𝘆𝘀𝘁𝗲𝗺 𝗗𝗲𝘀𝗶𝗴𝗻 interviews isn't because you haven’t studied countless case studies or designed a multitude of systems.

It is because you haven't mastered the core concepts.

I'm sharing the best resources for system design:

One project I would highly recommend, if you haven't done it already, is to build an HTTP web server from scratch.
