Nothing wrong with learning Javascript and Ruby or Python off the bat instead of starting with something like Java or C/C++. But you might want to start the course with stuff like programming language basics, database basics, and SQL if they're coming from non-programming positions.

It's also a little overkill to cover Django, Rails, AND Node.js in one course, isn't it?

I guess I'm not sure if the ad is targeted at Citigroup's software/IT people (who already know a lot of this stuff and are probably not the folks getting laid off) or the other (finance/accounting/admin/sales/customer service/operations) people (who probably need to start from the square-one basics of web programming).
