Social engineering training by Red Team Security

I've recently taken the Social Engineering Expert course from them and it was good, I was familiar with the topic already but the content was a good refresher on some topics and added more insights in some other areas, from the perspective of a red team engagement. Not highly technical, it goes over the entire range of social engineering activities, so it's not focusing on specific tools. What I liked most were the document templates provided for different parts of an engagement.

Literally one of the worst books I've ever read: Both visually and content wise.
Security Engineer/Analyst/Geek, Red & Blue Teams
OSCP, GCFA, GWAPT, CISSP, OSWP, AWS SA-A, AWS Security, Sec+, Linux+, CCNA Cyber Ops, CCSK
2021 goals: maybe AWAE or SLAE, bunch o' courses and red team labs?
Interesting comment about the book, I was actually wondering whether to try it. He is indeed the author of that book.
