Unprofessional employees with lack of good manner.
They asked questions about my current company information and business insights, how many people we are working in the deparmant, what is our jobs and secret infos about our process etc.
I didnt answer this type of questions because its against the every current employees aggrement with company. Also it isnt professional ethics. But they keep pushing me to answer it. That was the most unprofessional interview i have ever been.
