Mock Interview - System Design
45 minutes with a real system design question from our collection: clarify requirements, sketch architecture, deep-dive into components, discuss trade-offs. Tailored to your level.
Who it's for
- You have a system design interview coming up at Senior, Staff, or Principal level
- You pass coding rounds but get rejected on architecture questions
- You can build systems but struggle to explain your decisions in a structured way under time pressure
- You want feedback on completeness, trade-off communication, and depth of your deep dives
What you get
- 45-minute system design interview with a question from our collection of real interview questions
- Full flow: requirements clarification, high-level architecture, deep dives, trade-off discussion
- Task tailored to your seniority level (Senior, Staff, Principal) and target company
- 15 minutes of feedback on structure, trade-off communication, and whether you hit the right depth
- Follow-up support via email
Outcome
You know whether your approach has the expected depth, whether you communicate trade-offs convincingly, and where you stand compared to successful candidates. You have concrete areas to practise before the real interview.
When it fits, when it doesn't
Good fit if:
- You have a system design interview ahead and want to realistically practise the flow
- You need Senior+ level feedback, not general architecture theory
- You want a one-time performance assessment
Better a programme if:
- You need to prepare for multiple late-stage interview rounds simultaneously
- You also need positioning and salary negotiation at senior level
- You're targeting 120k+ and need an overall application strategy
Then the Move Up or Elite Search Programme is a better fit.
