I applied online. The process took 1 day. I interviewed at Mars & Co (London, England) in Nov 2016
Interview
Applied through the website and was contacted for a first round interview at their London office. Interview consisted of two one-to-one sessions: one discussing motivation with a more senior employee and the other going through a case study.
They said they would contact me with either a follow-up invitation or feedback. I have not heard back since.
Generally quite an underwhelming experience. The employees/interviewers lacked energy and the entire experience didn't leave me with the best impression of the company.
Interview questions [1]
Question 1
Standard motivation questions: 'Why Consulting?', 'Why Mars & Co.?', 'What other companies have you applied for?'.
