It's very easy to search for an employee, find their employment information such as contact info or work history within minutes - there are also filters to narrow down your search even more! I've used this software when searching for new employees at my previous workplace; it was extremely helpful since we have over 10K people in our organization.
Not all fields were required but they can easily sync with other applications/tools so that is no problem for me. The most useful tool is their recruitment platform, which allows you to find candidates from all around Europe in just few clicks! There are some minor issues with emails that could be fixed (it's sometimes difficult for me as an employer who lives outside of Spain). Their support team always answers very quickly when I have any doubt or problem related about my account so far it has been great experience working together! They also provide free training sessions if needed at no cost!!
