What easyJet publishes for new pilots
easyJet's public Become a Pilot page describes technical selection covering motor skills and spatial awareness, plus computer-based maths and technical skills. It then describes a virtual non-technical assessment with a presentation, group exercise and one-to-one interview.
The details depend on the vacancy
The wider pilot careers page describes an online test of verbal, numerical and spatial reasoning with a personality questionnaire. It also distinguishes non-technical assessment from the simulator assessment used for direct-entry Captains and Co-Pilots. Read the page for the route you are applying through; these descriptions are not one universal test format.
What you can practise on FlightDeck
FlightDeck has original drills for numerical reasoning, spatial work, memory, instrument scanning and multitasking. They provide general timed practice. They do not recreate easyJet's technical tests, simulator assessment or personality questionnaire.
What easyJet does not publish here
The public pages do not provide test questions, detailed timings, scoring rules or pass thresholds. The current vacancy and its candidate instructions are the source to follow if those details matter to your application.
