Frequently Asked Questions
What does 6-month access mean?
Your Pro subscription renews every 6 months automatically. You can cancel anytime from your dashboard — your access continues until the end of the billing period.
Why is everything at staff+ level?
Staff+ is the highest bar for ML system design interviews. By studying at this depth, you'll be over-prepared for any level — new grad, mid-level, or senior. Interviewers are always impressed by deeper-than-expected answers.
What does Lifetime include?
Everything in Pro, forever. You'll also get access to all future content we add — new questions, updated answers, and new features. It's the best value if you plan to interview again in the future.
Who writes the content?
Senior ML engineers with FAANG experience who have been through these interview loops themselves at multiple top companies. Not former engineers, not career coaches, not AI.
Do I need a plan for live mocks?
No, but we recommend it. Studying the content first makes mock sessions much more productive.
