I applied online. The process took 4 weeks. I interviewed at Merkle (London, England) in Sept 2018
Interview
The assessment centre was very relaxed. Started with an intro presentation a one to one interview. Then a few ice breakers which just involved answering a few questions around the group- most interesting thing thats happened to you, something you would like to do in the future. Then finally group exercise- was a survival task.
