I had about one interview a week, with one being a writing assignment, and received the final notice on the job. One interview was a screening. The second was meeting with the Director and Senior VP. The third and final was a meeting with the full team. Overall, I received prompt responses on moving to the next round and found the process to be respectful of the candidate's time and effort.

Initial screening and writing test, but then ghosted. I expected much more from a non-profit run by such high-profile individuals. Terrible treatment of potential candidates, and even if there's no interest, at least update accordingly. Highly unprofessional.
