Whole process took around 2 months. Applied in January and invited for a video interview around 4 weeks later. Following the video interview, invited to assessment centre a week later. The whole assessment centre took around 2 hours, firstly with a brief introduction to the company, their projects, and values. Followed by a group exercise and then rounded off with a one-to-one interview with a senior engineer and graduate engineer related to the position. Touched briefly on my CV and asked a number of competency type questions and one technical question.
