Pros
Co-workers were nice. They tried to make you feel comfortable. Lots of talking involved. You could find yourself blending into the company culture quickly. Interview process was easy. Almost everyone who went there (with or without experience) would get an opportunity to be trained. Interactions with people on the streets could be interesting.
Cons
A small office that looked very unorganized. Things were everywhere. Only 1 table for general meetings. Training/Orientation was not effective. Often a good idea to rely on yourself. Although the company said itself as the world's leading independent environmental organization, lots of people on the streets knew little to nothing. There's no where to place your personal belongings like your bag while working. It's better not to bring anything but yourself. Otherwise, you must take the risk for someone stealing your stuff if you decided to put them aside on a crowded street. There's a quota you would need to fulfill each day/week (the number of people you've stopped & signed up). Many co-workers were smokers. They did smoke a lot (could be the stress from the quota thing). So It could be tough to work around them without suffering from secondhand smoke. Last but not least, be prepared for back and leg pain for standing long hours.
