I applied online. The process took 4 weeks. I interviewed at Teneo (London, England) in Apr 2021
Interview
1) Telephone Chat (10mins) on motivations
2) 1 'sort-off' a case study, 1 'cv' case study.
Case study is a couple of slides of powerpoint, pretty much purely data analysis. There were two tables for you to look at (with plenty of unnecessary information). Don't worry about structure (like MBB cases) - just look at table and answer question.
CV interview - 1/2 was on a company that you like - and why you like them. and more general discussion on how they can grow/what they're doing well etc.
Overall decent enough process, quick feedback received.
It was a three turned into four stage process which involved a timed written task online which included writing a press release and social media post along with draft emails
Good and fun. Not too hard cases. Friendly interviewers. Straightforward process. Would recommend applying. 2 final round cases. 1 market sizing for first round. Overall enjoyed it a lot lot yes
The online exam and the online interview were tough but fair. The waiting time for the response to the first round was a bit longer than one would hope for.
