3.5/5

Strong cognitive planning and sound instincts on discretion, but struggles to translate principles into concrete execution. Written responses stay abstract. Knows what ‘good’ looks like conceptually, but has not yet developed the operational muscle to execute crisp staff work under pressure.

Competencies

Prioritization under conflict4.0
Discretion & information hygiene4.0
Stakeholder communication3.0
Executive leverage3.0
Operational fluency4.0

Strengths

Exceptional planning accuracy and adaptive prioritization. Strong discretion instincts. Sound judgment on objective priority calls.

Development areas

Written communication is template-level and lacks concrete execution detail. Defaults to ‘judgment call’ framing without demonstrating how judgment gets applied.

Planning & Sequencing

97% Strong

Plans with discipline and executes cleanly under time pressure.

Deliberation

Pauses to orient before committing, protects against premature action.

Complexity response

Invests more thought as difficulty increases, reads the room on harder asks.

Execution quality

Maintains accuracy under constraints, few slips or rework.

Why this matters

Every hiring team has been through this. Four rounds, glowing feedback, unanimous offer. Three months in, the fit isn't there. The process wasn't broken. Interviews measure how someone interviews, not how they perform under real world pressure.

Blackbook Assess puts every shortlisted candidate through the situations the role will actually throw at them. Real briefs, real trade-offs, real constraints. Their work is scored against a fixed rubric.

Inside the assessment

Four question types.
One signal.

The candidate is given a scenario and has to write their answer. Not a bullet list, not a template. Real thinking in their own words, under time pressure. We read for judgment, sequencing, and the willingness to make a call.

First scenario.

Scenario

Your CEO is mid-flight to a board offsite. Legal just emailed a draft 8-K related to a leadership change. PR wants a holding statement. The CFO asks you to hold everything until we land.

What do you do in the next 30 minutes, and what do you explicitly not do? Be concrete about who you involve and what you protect.

From our latest EA round

of candidates earned a ‘Strong Yes’ hiring signal.

The bar holds.
Round after round.

In our latest EA round, 7% of candidates earned a ‘Strong Yes’. The bar is calibrated to what actually separates the best EAs in the market, and it doesn’t move to fit the field.

The two competencies that separated them were commercial acumen and thinking ahead. Both are what the market rewards at the top. Both are hard to read in an interview. The assessment measures both.

We also watch how candidates behave between rounds. How they follow up. How they handle a brief that shifts. How they behave when nothing is being scored. It usually tells us more than the interviews do, and the best behave the same either way.
