Has anyone completed PA Consulting's 24-hour case interview (especially for Defence & Security)? What was the case format, expected deliverables, and what did the assessors focus on during the presentation and Q&A?

Hi,
I'm currently interviewing for a Management Consultant position within Defence & Security at PA Consulting.

Has anyone been through this stage, or something similar at PA? I'd really appreciate any insights into:

• What the case was like (strategy, transformation, operations, etc.)
• What the expected deliverables were (PowerPoint, memo, Excel, etc.)
• How the presentation and Q&A were structured
• What the interviewers focused on most

I'm not looking for confidential information—just general advice on what to expect and how best to prepare.

Thanks in advance!
