Applied through LinkedIn easy apply. Job poster arranged an informal telephone interview to get an overview of my background as my degree was in aerospace engineering. A month or so later, got a response and a case study interview with one of their consultants was scheduled. This included a 10-15 min formal telephone interview followed by a 45min to 1 hour long case study, which was described over the phone. Case study involved a market sizing for a theme park/roller coaster in a particular city. Not that difficult, however was under prepared therefore couldn't complete it.
