Maybe for quantitative roles, but not necessarily other roles.
And how do I know that your course is ‘recognised’ by recruiters other than your word? It could be, but also it could not be, in which case I may as well self-teach.
The course Dr. Duffy posted is pretty well known.
This is a bit creepy, but also just qualifies as due diligence in job searching/networking given the internet is as connected as it is. If you go through linked in, or other avenues, Dr. Duffy is very well connected with other's in the quant world. That's actually his course he linked, this site (the largest quant site I've found, in English at least, not sure about the Chinese ones) partnered with him, and the perennially top ranked FE program, to create it. And this site gets good traffic across time, and has an established reputation.
There are almost 40,000 members, and the member-guest ratio is typically over 4x. Due to the nature of the site, everyone who visits this place more than once or twice is either in the industry already, going to be in the industry soon, or wants to be in the industry. One of those members is
@Eric Jacquier (who just replied to your post). He the executive director of Boston's Masters program in this area. And almost all of these people probably know what the course is, and what it gives you, because it has good word of mouth and because Dr. Duffy posts it in reply to every single coding question (He is very persistent in this).
Someone else can chime in, but that's what I've learned from just a couple days as a member and some very basic google searches.
