My impression is that this is geared towards those trying to enter the industry, that have no academic experience with CS, and not for those already established.

Realizing this, I'd say it's enough. There are plenty of companies that don't even give coding questions, and many more that don't go beyond what's listed in the article. The only exceptions would obviously be what are considered top tier companies such as FAANG, Airbnb, Uber, etc.

I would definitely agree with your assessment of the target audience. I'm not sure if it's enough, though (depending on what it's enough for).

I think it's enough for someone who is just trying to understand the basics, but I wouldn't feel comfortable hiring someone for a qualified position who only just learned all of this (maybe just for the interview).
