System Design Mock Interview + Feedback
Find the gaps in your system design interview approach before your next interview. Work through a realistic design question with an engineer who has interviewed candidates at Amazon and Square. This package is for software engineers who have already studied system design and want a focused practice round. One 60-minute live session includes: - A brief alignment on your target role and experience. - Approximately 40 minutes of timed system design practice. - A debrief within the remaining session time, covering requirements, architecture, tradeoffs, scalability, and communication. - Your highest-priority improvements and independent practice steps, discussed together. The mock and feedback fit within the same 60-minute session. The question is a practice scenario, not confidential company interview material.
What's included
One 60-minute live, one-to-one session, scheduled by mutual availability. Bring your target role and be ready to sketch a design and explain your reasoning. You capture your feedback and action notes during the debrief.
- One realistic system design mock interview with a live, specific feedback debrief.
- A prioritized list of strengths, gaps, and next practice steps developed during the session.

Interview Coaching | Former Amazon & Square Interviewer
I'm Rohit, a software engineer and interview coach with experience at Amazon, Square, and Citrix. I've interviewed candidates at Amazon and Square, coached more than 100 people, and prepared for many interviews myself. I hold a master's degree in Computer Science from Texas A&M University and co-created System Design Masterclass with the Sweet Codey team. What we can work on: - Coding interviews: problem-solving, complexity analysis, testing, and explaining your approach. - Behavioral interviews: clear stories about ownership, collaboration, challenges, and impact. - Interview strategy: identify gaps and prioritize your preparation for a target role. - Technical communication and system design: explain decisions, compare tradeoffs, and respond to follow-up questions. We agree on a clear focus for each session, practice together, and finish with specific feedback and next steps. Bring your target role, interview stage, and the areas you find difficult. Sessions are practical and tailored to your needs, with feedback delivered during our booked time.
