Is it acceptable for a recruiter to ask for my date of birth? Am I jeopardizing my chances of getting an interview by being hesitant to provide it?

Update: It’s been two weeks, and I haven’t heard anything—I’m feeling a mix of emotions, primarily disappointment 😂😞.

To give you some context, this is a recruiter from the EU, so they might have different rules and regulations. We had a positive initial screening call, which I really enjoyed, and the recruiter seemed very friendly. However, they later reached out to ask for my date of birth, stating it was necessary to complete my application in their system.

I was a bit wary about sharing that information and asked if they needed it to meet a specific age requirement for the position, but they assured me that wasn’t the case. While I eventually provided my date of birth, I made sure to communicate my discomfort.

Now I’m wondering if I hurt my chances of moving forward in the interview process by expressing my hesitation. Did I give the recruiter the impression that I didn’t trust them? Could my age potentially be a factor against me for this corporate role?
