I applied through a recruiter. The process took 6 months. I interviewed at Mercury Public Affairs (London, England) in Jun 2020
Interview
First round and second round interviews on Zoom with the MDs (during the pandemic to be fair); a writing test; a team chemistry meeting; a long delayed meeting with a senior; eventually just didn't hear back; think the London office executed a team move shortly later. Overall a frustrating experience but I can see why it all happened that way in retrospect.
