System Design
Blob Store
Learn to design a scalable, reliable, and highly available blob store system through a structured, rigorous, and thought-provoking series of questions.
Interview Details

Step into a realistic system design interview focused on building a scalable, reliable blob store—just like those powering cloud giants. You'll be guided through a structured series of questions that simulate a real-world technical interview, progressing from defining requirements to high-level and detailed architecture. Expect to illustrate your ideas, justify design choices, and handle curveball questions that test your depth and adaptability. The experience is designed to challenge you, probe your understanding, and mirror the rigor of top-tier tech interviews.

Get ready to engage in a dynamic conversation where your responses shape the flow. You'll be asked to sketch diagrams, defend your decisions, and refine your design based on feedback. The session is fast-paced, inquisitive, and always focused on practical, real-world scenarios.

Here’s what you’ll sharpen during this session:

  • Defining and prioritizing functional and non-functional requirements for a blob store.
  • Designing scalable, highly available architectures and illustrating them clearly.
  • Justifying technology choices for APIs, databases, and storage strategies.
  • Handling trade-offs and scenario-based challenges under time pressure.

By the end, you'll be better equipped to tackle system design interviews for storage platforms, confidently communicate your ideas, and handle tough follow-up questions with clarity.
