head hunter, followed by a geometric test and telephone interview. Face-to0face interview at their Slough office

Interview process is challenging but expected as everything you need to know is available online. They will schedule you with 4 employees from the team or organization you will work with and 1 completely separated from your organization as a "bar raiser". No need to work to impress one specific person, know 12-14 differentiated STAR formatted stories by memory.
