I did a fair amount of investigating ATS systems, and Greenhouse ultimately won my business and has kept it for a several reasons.
1. Customer Service. Their sales team understood the difference between availability, persistence and harassment. Their implementation specialists are patient, articulate, empathetic, easily accessible and even open to product improvement suggestions. Support tickets are handled quickly and when the matter is a more complex tool-wide programming solve, they still communicate the outcome to you---even months later!!
2. UI and UX. It's sexy, intuitive, and easy to use. Trying to get timely candidate feedback from super busy creative people, many of whom are naturally disorganized, has meant the simplicity of Greenhouse has been a godsend. They even like using it because its pretty. Anything to made the horse led to water drink, ya know?
3.Customization. I love that I can change make both minor tweaks and major adjustments to scorecards, job posts, work flow and hiring teams with zero headache. We can also put our unique brand voice on everything our internal team and candidates see, so nothing about it feels robotic.
4. Candidate Experience. It's fast, simple, and clear on the receiving end, which is the most important part. Feedback from our candidates, even from rejected candidates, has been glowing since we started using Greenhouse---a vast improvement over our previous MO.
5. Ease of Communications. Communicating to and about candidates is simple and fluid, AND can all activity around a candidate is logged, so you check and double check last communications---key when you have a large pool and fast moving process. It's also web based, so use it from your phone, home computer or anywhere that's not your desk.
The only drawback is that the flexibility in the rest of the tool is not represented in the reporting. The reports can be a little difficult to decipher and there are some sets of data not offered that would be quite useful, though not critical. On the whole, the reporting features are more than adequate, but relative to the awesomeness of the tool and service otherwise, it would step up a bit.
