Would-be software engineers at Dyson will be challenged to a cryptic codebreaking trial this weekend which could lead to a job with the firm.
They'll be tested via a series of "Smart Rooms" - a shifting environment generating new puzzles that will assess thought processes, teamwork and creativity.
The pop-up puzzle, in south London, will see the contestants either work as a team or individually to solve the challenges in each room. Winners will be given a Dyson 360 Eye robotic vacuum cleaner signed by the company's founder, James Dyson.

Dyson is looking to hire 110 software engineers in a bid to grow its workforce from 2,500 staff to 3,000 by 2021.
