I applied for the position via Jopwell and heard back shortly after to set up standard phone screen. Why the role, company, experience, strengths and weaknesses.
Second round included three segments. A one-on-one round with manager talking about your experience in greater detail and how it relates to Kepler's core values, followed by a marketing scenario. Pick a company and "how would you market it?" Think who, how and why. It really helps to research the company and ask question on the phone screen. Second part was a data study case analyzing google analytics metrics, doing simple calculations and offering recommendations based on your insight. Last part of that round is a 5 minute presentation to three members on any topic of your choosing and answering questions.
After the second round I was told the position had been filled but they would reach back out if something opened up. To my surprise, they actually followed up about a month later and I interviewed with a Manager. Very conversational and just spoke deeper about why you want to work at Kepler, why media, and what you bring to the table.
After about two months I didn't get an offer but I still enjoyed the process and learned a lot.
