I applied through university. The process took 1 day. I interviewed at RDT (London, England) in Feb 2016
Interview
Invited to their centre just outside London.
First a tour around the facility, explaining the work done, some of the products and the teams.
Then a 1to1 interview, not technical but with some questions of the type "what would you do if..", nothing to be scared about.
Interview questions [1]
Question 1
What do you think are important biometrics and parameters to be recorded from this machine (look up different machines they have)
