What gets scored in every session

Dimension What it measures How to answer
Model Rigor Was your model structured correctly? We probe for driver identification, assumption clarity, and scenario analysis, not just output accuracy. Assumption transparency, key driver naming
Assumption Clarity Can you name and defend your key assumptions? We flag answers where assumptions are implicit or generic rather than explicitly stated. Explicit assumption naming, source or rationale
Business Judgment Did your analysis lead to a clear recommendation? 'Here's what the model shows' is a weak ending. We score whether you took a position. Recommendation presence, business framing
Impact Quantification What did the analysis change? We look for a downstream business outcome, a decision made, a project stopped, costs saved. Decision impact, $ or % savings, outcome specificity

How a session works

Step 1: Get your Lam Research Finance question

You are assigned questions based on where candidates for this role typically struggle most. Each session starts fresh with a new question targeting a different evaluation dimension.

Step 2: Answer by voice

Speak your answer as you would in a real interview. The AI listens for STAR structure and evaluation dimension signals in real time as you speak.

Step 3: Get scored dimension by dimension

Instant scores across all four rubric dimensions. Each gets a score, a flagged weakness, and a specific sentence-level fix, not 'be more specific' but which sentence to rewrite and why.

Step 4: Re-answer and track improvement

Revise based on feedback and answer again. See the before/after score change. Your weakness profile updates across sessions so practice becomes more targeted over time.
