5.5 hour in office interview
Feedback:
They mentioned that this was their first time hiring a marketer and it was clear. If you are hiring an experienced marketer, you can ask to see their previous work instead of asking for home work and ideas.
Culture fit is important here. They seen a bit cultish. A young person that is willing to "figure things out" would be a good fit here. They don't have an experienced product person, but they only want their marketer to focus on awareness/the top of the funnel.
It is my sense that they don't really understand what it takes to get a startup to become a household name. I am not sure that want someone to get them there. They are looking for the they thing that will move the needle, not a holistic approach to marketing.
They offer lunch in the day long interview, but it is hard to eat when you are talking. I would recommend breaking that part of the interview up and have the candidate meet the full team after the key people have decided if they want to work with the person. I was tired and hungry by 2pm and could have used a 30 min break to eat and get some fresh air.
