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.
