Dream11 interview experience

SDE 1 (frontend) interview experience at Dream11

My Interview Experience at Dream11 (SDE 1 Frontend)

I had applied long back for SDE 1 Frontend role at Dream11. At that time, I had around 1+ years of experience working as a frontend developer in a product-based company.
Overall, the process had 4 rounds – mix of DSA, JavaScript, machine coding, React fundamentals and finally HR.

Round 1 – DSA

The first round was purely Data Structures & Algorithms.
I was asked 2 coding questions:

  • Both were string based.
  • Difficulty was medium–hard.
  • One required use of stack.
  • Another was based on permutation/combination logic.

It took me some time, but I managed to solve both.

👉 Tip: For Dream11, be strong in string manipulation + stack-based problems.

Round 2 – Machine Coding + JS Concepts

This round was a blend of hands-on coding and JavaScript theory.

Tasks I faced:

  • Implement a polyfill of Promise.
  • Some JavaScript output-based questions covering:
    • Closures
    • call, apply, bind
    • async/await

👉 Tip: Brush up on JS internals and be comfortable writing polyfills.

Round 3 – Hiring Manager

This round was more about real-world frontend + React knowledge.

Some key questions:

  • How can you optimise large lists in React Native?
    • I explained virtualisation and how it improves performance.
  • Difference between useEffect and useLayoutEffect.
  • General discussion on React lifecycle and performance best practices.

👉 Tip: Expect performance and optimisation-based questions beyond just coding.

Round 4 – HR

This was the final round.
Mostly behavioural and fitment questions, like:

  • Why Dream11?
  • My previous work experience.
  • Career aspirations.

Nothing too technical here.

Final verdict: Got an offer & later joined them as SDE 1 (frontend)

Preparation Resources

Here are some resources that helped me in preparation and I would recommend:

📘 DSA

⚡ JavaScript (Core + Polyfills)

⚛ React & React Native

🎥 YouTube Playlists

Final Thoughts

My overall experience with Dream11 was good. The questions were fair and focused on:

  • DSA fundamentals
  • JavaScript depth
  • Practical React/React Native performance

If you’re preparing, I would say focus on strong basics, hands-on coding, and performance optimisations.
