Understanding the Implications of an NDA

I need some guidance on the effects of signing a Non-Disclosure Agreement (NDA). I’m in the process of searching for a full-time job and considering an internship that requires me to sign an NDA and a Confidentiality Agreement before any discussions. I’m concerned about how this might impact my job prospects with other companies in the same industry. Can I sign the NDA confidently, knowing it won’t hinder my chances for future full-time roles in similar sectors? Any insights would be greatly appreciated!
