The interview process is quite involved, consisting of three phases. The first two are pretty standard - a phone screening followed by an interview with someone related to the department hiring. Following that is a series of 4 interviews that also include a case study. Those interviews are generally held on the same day over a few hours, though there's flexibility depending on everyone's schedule.

Be warned: this another company asking for you to create new intellectual property and perform free work in the interview process under the guise of a "Take home case to generate insights on relevant projects." Somehow walking them through a detailed report of a major SEO project that was already accomplished and for which I was paid, wasn't enough for them to gauge my "ability to generate insights." We all deserve better as interview candidates.
