Challenging but fair - consisted of a recruitment screening, a brief personality assessment, interviews with key department leads, and a small practical focused on thought process and frameworks.
Pretty standard interview for the marketing side, was focused around a mix of practical knowledge and systems thinking on how to integrate marketing into the organization while achieving company goals.
Company emphasizes specific personality and cultural aspects to ensure cohesion - very positive experience and that focus shone through a lot of the interview process. Very open, diverse, and inclusive environment that stands in contrast to a lot of "techy/startup" interviews I've had.
