I applied through other source. The process took 3 days. I interviewed at Foundry (London, England) in Dec 2017
Interview
I first had a quick chat with the hr, then had a hangout interview they assessed my candidature. Then finally I had a F2F interview where they gave a paper with few questions and then we talk about it. There were really nice, one of test was to know how I would face different situation and challenges.
