I really do appreciate your effort for highlighting only essentials tools for becoming a fit for the DevOps role, but, to be really honest, this isn't the MVP (Minimum Viable Person) for the job post/working scenario. You must have these below listed skills as well.

1. Linux Administration Skills

2. Networking Knowledge ( And I mean should be good enough to calculate CIDR, routing, protocols and many others)

3. Knowledge for Operating System features.

Your given tools might be enough to land into a fancy DevOps role, but within inside, the person would surely be aware, that it isn't enough as an MVP. And you should get your hands dirty in this as well.

Loved your blog.
