The Interview process was a two part process.
I initially had a general interview with the direct and a manager of the client management team. This lasted about 30-40 minutes, and was very easy going.
I was then asked to prepare a presentation and sample media plan for the second round interview, which included speaking to the same two people as my first round, as well as a member of the HR team. This interview lasted about 45-60 mins.
Apart from the amount of work involved to prepare for the second round interview, the presentation and resulting questions were all very manageable and all interviewers were pleasant and receptive.
