Using Effy (ex Paser), we have automated many HR processes. For example, all kinds of absences, hiring applications, offboarding, relocation, the ability to recommend a friend for a certain vacancy, notifications about birthdays and the end of the probationary period for newcomers, a 360-degree feedback, etc.
But the real pleasure is conducting surveys through Effy (ex Pacer)! Firstly, it is possible to customize the report template for each specific survey, and secondly, you receive a report with many parameters based on the employee's personal cards. By each of these parameters, there is the possibility to filter the data and build hypotheses.
But the main advantage of Effy is customer support and readiness to find a solution to any type of request, even in the middle of the night :)
