The Interview Process

Data Assessment

You are given a massive dataset (e.g., anonymized Oyster card journeys or traffic sensor data) and asked to extract insights using SQL, Python, or specialized transport modeling software (like Emme or VISSIM).

Presentation

You must present your findings to a panel, translating complex statistical models into actionable policy recommendations (e.g., 'Should we add a bus lane here?').

Competency Interview

Assessing your attention to detail and ability to handle political pressure. TfL data often dictates highly controversial choices (like the ULEZ expansion).

1We are considering closing a major tube station for 6 months for escalator repairs. Walk me through exactly what data you would pull to model the resulting congestion on the surrounding bus network. (Analytical Modeling / Domain Knowledge)

2(Behaviour: Fair and Consistent) A local politician is aggressively demanding that you alter your data report because it shows their proposed new cycle lane will actually increase journey times for drivers. How do you handle this? (Integrity / Political Navigation)
