Backend System Design Mock Interview 💻

I’m currently a Senior Software Engineer at HubSpot with over 8.5 years of experience. Having taken and attended 100+ interviews throughout my career, I’ve gained a strong understanding of what top tech companies look for in system design interviews across different levels (Entry, Senior I, Senior II).

In this session, we’ll walk through a backend system design problem together. I’ll share practical tips, highlight common pitfalls, and help you structure your approach to stand out in real interviews.

Session structure:

• 5 mins – Introduction
• 45 mins – Design Discussion
• 10-15 mins – Feedback + Q&A

Note: This session focuses on high-level backend design and is not frontend-specific.
