I applied online. The process took 2 months. I interviewed at Leonardo (Yeovil, England) in Feb 2018
Interview
Applied online, invited to assessment centre in Yeovil after a month. Really positive day, all about them learning about you and making sure you're a good fit for the company.
The interview process at leonardo seems to be a series of interviews and online assessments, which are all quite easy and self explanatory. I completed the online interviews and am currently waiting to hear back
