I applied online. The process took 2 weeks. I interviewed at Merkle (London, England) in Oct 2017
Interview
I think I was fast tracked as I had applied to their internship the year before. After sending off my CV I was invited to their office in London for a panel interview (just me and two Merkle Periscopix employees).
Interview questions [1]
Question 1
They gave me a piece of paper and pen, and told me calculate the total annual revenue for a cinema. I was given no further context.
