In the free trial you get a decent idea for what Uwi can do and Uwi might already be able to recruit some candidates for you, although there are some limitations in the trial.
You can run 3 positions with a limited amount of profiles screened (~50 profiles per position). You can also let Uwi reach out to candidates that you approve.
When you are on a premium plan, you get the amount of indicated position slots based on the plan you choose and there are no limits to the amount of profiles screened and reached.
