This process was by far one of the most frustrating experiences I've been through in my career. Not only was the hiring process comically long for an email marketing firm, but they also require candidates to, in essence, give a free consulting presentation to a broader panel. The prompt essentially asks candidates to suggest feature improvements for an existing product, as well as write out requirements for said enhancements. By my estimate, asking candidates to do free work is an ethically gray area and morally suspect. What's even more frustrating is that of the handful of final candidates in last round, none were hired and the company closed the position. As such, it reinforces two thoughts: First, that the company had no intentions of bringing on a senior PM and crowdsourced free consultation, and two, that the hiring team has absolutely no clue what they're looking for in a candidate -- and what they value most is their own inflated sense of self-worth. Given this experience I would strongly advise caution to any product folks looking to apply. While I hope I'm wrong, I wouldn't be surprised if the hiring team gives similar treatment to future candidates as well.
