I applied online. The process took 2 months. I interviewed at Buro Happold (Bath, England) in Feb 2017
Interview
The entire interview lasted for about 30 minutes. I had to do a 5-10 min presentation on the role of a consultant engineer in a sustainable future, which I found very interesting myself. The presentation was followed by some competency based questions, questions about projects I was part of at university and extracurricular activities.
