I applied online. The process took 1 day. I interviewed at Global App Testing (Kings Cross, England) in Oct 2018
Interview
After a long Friday from 9:30 to 17:00 at Global App Testing, the hiring managers told us to wait for an answer within the next Monday.
No answer from Global App Testing yet, but a new job post for the same position after two weeks from the Recruitment Day. Definitely not a nice way to know you were not selected.
