I applied online. The process took 2 weeks. I interviewed at Insight (Uxbridge, England) in Aug 2018
Interview
Simple process, 1 phone interview that led to an interview on site. The questions were standard but asked in a more human context. Interviewed by 3 different people from 3 different sites, joined in a tele-conference. Very polite but they were in rush, hence I couldn't take my time to present examples in my answers.
