On one day, I had an 1:1 interview with a director, another director, and analyst. I took excel test and it was not difficult. People were very nice during the interview.

Initially, an in-house recruiter got in touch with me via LinkedIn. After a brief phone screening/interview, I was invited to an in-person interview session on site where I interviewed with the recruiter again as well as with the two team members I was going to work with. Finally, I was invited to another interview with the VP of marketing. The whole interviewing experience was very fair and cannot necessarily be described as a "grilling" process.
