Merkle interview questions

I applied online and they were pretty responsive, asking for a telephone interview within the same week. After that, a skype interview was organised in place of a face to face. They were very personable and made me feel as if, at times, I was just having a chat.

Multiple phone interviews with the recruiter and hiring manager before coming in to meet the team. After I met the team in person (twice), I was asked to return to do a presentation to a large group. I was told this is a 'Merkle' requirement and SOP. I was not given much direction on the presentation (topic, format, etc.) so went with my best guess. I did get the job so assume my 'guess' worked.
