A regular consulting interview, with an estimation/ market sizing question, CV talk and another business problem focused more on strategic considerations. The interviewers were very nice and engaging, and had a nice chat with them about Teneo. Definitely learn as much as you can about the firm before the interview, as some of the questions were directed at that.
I applied online. The process took 1 week. I interviewed at Teneo (London, England) in Feb 2018
Interview
There is an online application which involves submitting a CV and cover letter, followed by a numerical test and a phone interview a few days later. In the phone interview you can take time to prepare your answer before answering. The whole thing lasted less than 15 minutes.
