A presentation + competency questions. Some questions on things in my CV. Presentation was on a technical test sent before interview with an energy challenge. Short time for my questions. Interviewers were all consultants.
I applied through a staffing agency. The process took 3 weeks. I interviewed at City Science (Exeter, England) in Jan 2017
Interview
First Stage: Telephone Interview and Data Science assessment.
Second Stage: 3 face to face interviews on premises with the last one being a panel interview and a presentation based on OR assessment given.
The data science assessment of the first stage was not directly relevant to the position. The OR assessment was more in line with what was expected from the role.
The second assessment required a lot of time, coding and research which was not easy to do with a full time job.
They reimbursed travel expenses, which was very positive.
