What gets scored in every session

Specific, sentence-level feedback.

Dimension What it measures How to answer
Process Clarity Can you describe a process clearly, inputs, steps, outputs, failure points? We score the technical clarity of your process description. Process stages named, failure mode awareness
Efficiency Impact What improved and by how much? We flag stories without a quantified before/after, cost per unit, throughput, error rate, or cycle time. % improvement, time/cost delta, error reduction
Execution Ownership Did you design and implement the change, or observe it? We detect whether you were the actor or the narrator in your own story. Personal action verbs, decision ownership
STAR Balance Operations stories often have strong Situations and weak Results. We flag imbalanced structures and help you invest more in Action and Result. STAR proportion, Result specificity

How a session works

Step 1: Get your HF Sinclair Operations 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.
