🟢 Blinkit Interview Experience – Round 1 (DSA + System Design Hybrid)

Hi everyone,
Sharing my Blinkit interview experience for anyone preparing or curious about their process.

📞 HR Call

I first received a call from HR where they explained the role, basic expectations, and the interview structure. After confirming my availability, they scheduled Round 1 (Technical).

🧠 Round 1 – Technical Interview

The first round was DSA-based but with a system-design flavor.

The main problem was to design an Oncall System

It was divided into multiple sub-parts, each building on the previous one

The focus was on:

Data structures choice

Handling edge cases

Scalability and clarity of logic

I first explained my approach verbally, discussing how I would model the system, what data structures I would use, and how different operations would work.

After that, the interviewer asked me to write the complete code based on the approach I explained.

💡 Key Takeaways

Clearly explaining your thought process is very important

Even system-design-like problems can be DSA-heavy

Be prepared to convert your design into clean, working code

Hope this helps someone preparing for Blinkit interviews.
All the best! 🚀
