Applied online. About two weeks later they called me to set up a face to face interview. They flew me out to their site the next week. I met with the hiring manager and the lead engineer. The interview lasted about two hours in addition to them giving me a tour of the facility. I was told I would hear back from them in two weeks but that never happened.

It was a panel of 4 members from the IE team and HR. A lot of the behavioural questions were read off a sheet. Overall decent interview process. They asked me to analyse a couple of graphs and voice my thought process
