Forgot about this application until now.
The attachment literally told me to spend several hours on the it. I submitted everything and never heard back. Luckily found another job in the meantime.
Best part is the written assessment involved writing a basic workplan for the first 6 months of this potential job. Felt fishy at the time but I did it anyway. They probably just used my ideas and dumped the application.
There's also a chance this supposedly-community-serving non-profit is funded by Uber to fight against unionization efforts, something I didn't know until after I applied.
Looking back, the second paragraph of this email is so shitty.
