What do you like best?
It's simple and easy to use. New employees can be trained within a couple days or less to use it. Control over users and permissions. Decent price plan, and support for how it works. In other words they will help you understand how it works.
What do you dislike?
The reports that are built in. Be careful. Some numbers are dynamic , and some are static. Some are historical, some are now snapshots. CATS provides no report titles or descriptions that would tell you anything. The number in different screens don't gel with what they say either. Use API for reports , or use the report > general > users to see the true numbers based on the time frame and now. Just don't trust they are correct (the reports) Also some things only get recorded upon mouse click events. Meaning if you use the online application system, it will not show you numbers on what user got the most new application .. the web cant record the status .. cause it needs manual entry. Which defeats the point of the live site. . .Also support doesn't get technical, and neither can the staff. If you plan to use this for API and build something bigger . be aware they only have forums in which you can get tech help from. No internal support or devs it seems. Last note , if you want something to be fixed, or find a bug. You will need to gather mounds of evidence before they belive you.
Recommendations to others considering the product
Its a great system at a great price. However, ee careful with reports , they don't come right out and tell you what you are looking at per say. Be aware.
What business problems are you solving with the product? What benefits have you realized?
Recruiting, and staffing. Works well, we integrated with API. again be aware they may change the way the API works .. don't go too far beyond what the basics are. The built in reports are good for gauging direction ,, good or bad. Do not count on these numbers to reflect accuracy.
