Recruiter was very clear with what the interview process would include. kicked off with phone screen and then a number of various different interviews with hiring manager and skip levels.

Really quick process; I was contacted within a week of submitting my application and had a round scheduled with Brian, a talent recruiter at Klaviyo, almost immediately. I felt Brian was a world-class recruiter as he was very informed about the position, about the company, about PM's role in the organization and he set really clear expectations about the next steps. I actually noted that Glassdoor interview reviews stated that PM interviews could take weeks and had quite negative feedback, and he was able to speak to that and affirm to me that they'd made changes and the process was much quicker and clearer now. I didn't end up getting the job after round 2 (which I enjoyed! I spoke with a product lead / hiring manager, and although I do wish this interview had been a little sooner after round 1 it still wasn't an unreasonable gap between rounds), but Klaviyo was really quick to let me know that I was not moving forward. Brian provided additional feedback upon request. Figured I should leave a review here since I had a really positive experience, but they hired a candidate into the role before I got to the written assessment stage, so I can't speak to the full flow.
