First round of interview was in the morning - there were 16 of us and asked us to do informal, impromptu presentations (e.g. what is something you are passionate about?). It's a group interview and at one point they divide you into teams and get you to do a presentation on a company you think could use the Meltwater service. For the second round you get called back later that night and it's an hour long 3-on-1 interview, with you being asked questions by 3 employees. They definitely try to throw you off a little bit - not the easiest.
