Credit PE vs. traditional PE

I'm currently working at a traditional PE firm, and was reached out by headhunters on a few opportunities regarding the private investing arm of credit/special situations firm focused on distressed long-only PE and special situations lending.

I didn't find much information on credit PE funds, so was wondering if someone can provide thoughts/general overview on how the work itself compares between PE vs. credit PE, lifestyle, compensation, and whether these firms would want to hire only from people with credit backgrounds (e.g. Restructuring IBD).

Lastly, what should I do to prepare for any potential interview in this field?

Thanks in advance!
