Credit Fund Interviews Prep?

Hi all-

Reposting this in the hedge fund forum

I am interested in interviewing for credit funds in the near future and am wondering if the WSO PE interview guide would be worth it for me? I am currently in a debt focused role at a BB.

The WSO PE interview guide for $299 includes the following:

• 9 LBO Tests
• WSO Video Library - 1 Yr Access
• WSO Company Database - 1 Yr Access 
• 300+ PE interview Questions - Company DB
• 200+ Page PDF on PE Industry & Recruiting

While I believe the modeling in a credit fund should not be so intense, I am mainly looking for practice on modeling so I would imagine these would be somewhat relevant?

Additionally, I am interested in practice questions, I see in the list of included resources that the package has "300+ PE interview questions" - are these real questions that are generated by a team at WSO, or is it simply a collection of user-generated questions? Furthermore, are these questions technical in nature (in which case I would imagine could apply to credit as well.. for example some random technical on NOLs and the impact to modeling, or a question relating to operating leverage.. etc). 

Really mainly interested in the questions and modeling since I don't believe the other components would be incredibly relevant to credit funds. 

Any help or advice here would be much appreciated. If you can point me to sources for credit fund interviews that would be very helpful as well. 

Thanks
