I applied online. I interviewed at Interrupt Labs (London, England)
Interview
Interview mainly with the team about what they do and what you will be doing if you got the job. A lot of general VR specific stuff. It's not necessary to have experience with specialised field but would recommend having a general VR experience to get a role.
Interview questions [1]
Question 1
Will be specific to what team you will be working on, eg, Android, Embedded, Browser etc.
