I applied though a LinkedIN ad. I heard from HR about 3 days later and did a Round 1 interview. After that, I was invited to take an IQ/personality test online. Then I was invited to go into the office, where I interviewed with 4 people, including the head of HR. I was told that everyone liked me, but that I needed to meet more people. A week later I went into the office again, where I met with 4 more people. About a week after that, I was informed that they wanted to extend an offer. While I think I was probably interviewed by too many people (towards the 8th person they started repeating questions, and not knowing what else to ask), I was impressed by the thoroughness of the process. Generally speaking, the people seemed really nice and probably great to work with.

Phone screen followed by an HR interview, an interpersonal interview with a director, and a technical interview with a director. Recruiter and interviewers were mostly professional. After 3 rounds, I didn't get a heads up that I was getting a technical interview, so I was surprised when I came into the meeting. This threw me off my game and I didn't perform as well as I could've (plus, I had to do some of the math with a highlighter on my hand due to not being prepared). The questions aren't hard (think GMAT style questions and some marketing strategy questions), but because I was in my own head, I didn't do well. Recruiter never gave me a concrete rejection, just ghosted me. Overall, a long-ish interview process that could have some better communication about next steps and what is included in the technical assessment.
