Honestly, this was a highly disappointing interview process.
What Notion calls a "prioritization interview" is not a genuine prioritization interview by industry standards. Facebook, Amazon, Netflix, etc, all have these interview types and they're appropriately labeled/categorized, explained, and articulated to interviewees beforehand. Thus, I came into the interview unprepared for the interview type Notion had planned.
Furthermore, the additional details about the interview format within the resource site were minimal, ambiguous, and misleading. I hope you guys seriously reevaluate your resources and are able to better equip interviewees and set them up for success.
Just to cite an example of a better practice (by a much smaller start-up than Notion), interviewees receive a small deck breaking down the interview stages, attributes that are going to be tested across the interview, and the stakeholders holding interviews across the entire process.
Again, I felt short-changed in the process and I am candidly frustrated that I spent time preparing for a different interview type that left me feeling unprepared when I walked in.
