About this session

High-pressure, no-nonsense mock interviews and brutal, pinpoint diagnostics engineered exclusively for candidates facing imminent Onsite loops at top-tier tech companies.

If you have an upcoming interview and need to stress-test your readiness, this is a high-stakes simulation—not a generic chat. We will target your exact weak spots across four core pillars:

1. Product Sense & A/B Testing: Navigating tricky metric trade-offs, messy edge cases, and ambiguous experimentation frameworks.
2. High-Pressure Mock Simulation: Mirroring actual FAANG hiring committee-level pressure with a frame-by-frame critique.
3. Execution & Rigor: Eradicating statistical traps, optimization bottlenecks, and logic gaps.
4. Behavioral STAR Alignment: Polishing executive communication for senior and leadership-track expectations.

*Note: This session is built for candidates in active interview prep who want direct, unfiltered, and high-value feedback to clear the bar. You can choose one session focus or customize a combination based on your immediate onsite needs *

Your mentor

Hi there! I am Liming Liu, Data Scientist at Meta and former DS Manager. Having conducted numerous DS/DA interviews and mentored multiple candidates to land top offers, I specialize in high-pressure, no-nonsense FAANG mock interviews and brutal, pinpoint diagnostics.

Who this is for:
This mentorship is designed specifically for professionals with a 2+ year data background who are ready to put in the reps to land DS/DA roles. We don't do passive coaching; we execute.

Whether you need comprehensive monthly mentorship or a targeted onsite prep for a Data Scientist / Product Analytics role, I tailor my approach to your pace.

What we focus on:

🎯 Product Sense & A/B Testing Deep Dive: Experimentation framework, metric design and diagnose and trade-offs.
🔥 High-Pressure Mocks: Real-world simulation mirroring actual FAANG hiring committee-level pressure, complete with frame-by-frame critique.
⚙️ Execution & Rigor: Overcoming statistical traps and navigating messy edge cases.
🗣️ Behavioral & Leadership: Rigorous cross-functional conflict, impact storytelling & leadership alignment simulations.
