Before we begin the 30 fully explained TfL interview questions and answers, let’s touch briefly on TfL’s history.
A brief history of TfL London
TfL London was officially formed in 2000 as part of the Greater London Authority Act, bringing together several previously separate transport bodies. The goal was simple but ambitious: deliver a more coordinated, integrated and passenger-focused transport system across London. Over the decades, TfL has modernised the iconic Tube network, introduced the London Overground, expanded cycling infrastructure, rolled out contactless and Oyster payment systems, and transformed how Londoners travel. Today, TfL employs more than 28,000 people in roles essential for operational excellence, safety, engineering, maintenance, digital innovation, customer experience and long-term urban planning.
With such a large and diverse workforce, TfL interviews typically combine competence-based questions, scenario challenges and behavioural assessments — areas where structured interview coaching and professional interview training can make an enormous difference.
