I interviewed at Headland Consultancy (London, England)
Interview
Written test with a choice of questions to be completed in a set time, followed by 3/4 rounds of in-person interviews with a mix of management team, directors of the teams that you may work in, and a couple of people close to your level.
Three rounds and a written test. Two competency-based with more senior members of the team and one with peers of a similar level. Most questions about CV and general industry and job understanding.
