I will never understand GIT it is so confusing 🙃

Git commands I used 99% of the time being a Software Engineer for 2+ years with the working flow:

I have researched lots of top MNCs like Amazon, Microsoft, Google, Uber, Tiger Analytics, Databricks, etc., for Data Engineer roles (since it's booming) and found that here are some topics that are asked in every interview, both at the fresher and experienced levels.

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.

Here’s what’s inside👇

✅ 4-Step Roadmap (esp. if your interview is in 15 days)
✅ 15+ core concepts broken down in simple terms
✅ Basics → Advanced (CAP, Queues, Microservices, Caching, DBs, etc.)
✅ 50 System Design Q&A (with diagrams + examples)
✅ Ultimate Cheat Sheet for quick revisions

Don't aim for this:

Java - 25%
Spring Boot - 25%
Microservices - 25%
System Design - 25%

Aim for this:

Java - 100%

Master one skill deeply, then build around it!

Without Leetcode, you cannot pass interviews.

Without side projects, your resume will not stand out.

Should you focus on LeetCode or build another project? To get your first job, you need a mix of both.

But the real problem? Many people don’t know what to build.

I’ve been there too.. motivated to start coding but stuck staring at my screen, Googling "best programming projects" and eventually ending up watching YouTube videos instead.

This cycle continues until you start building.

To break this cycle, here’s a list of projects to boost your portfolio + DSA patterns to crack coding interviews.

Design Zomato? Design Netflix?

No, start with these 3 underrated problems.

Everyone jumps to building complicated systems on day one of system design prep.

But no one talks about the real learning in the underrated ones.

Here are 3 simple but most-asked problems to start with:

I wanted to learn Software Engineering, so I watched 100+ videos on YouTube.

80% of them were a complete waste of time.

But this 9-playlist will teach you more skills than a 4-year degree.
