Agreed, though I don't feel like a Full-Stack Engineer should do the DevOps Engineer job as seems to be required by this hiring manager. I am not saying you should not know the underlying component you are using in your stack though, just what you need to work on it, not how to administrate a large scale database deployment.
It seems that the world clearly lacks a definition of what Full-Stack Engineering really means ...
I wish. My recent task has been writing scripts to set up Postgres on a bare-bones linux server (including all security, software, users, nfs, hot backup servers, etc) and port an Oracle database over to the postgres database and update 1000s of oracle queries to work on postgres.
In my spare time I also had to create some new admin screens and do a bunch of back end work. I also created a bunch of new svg images for the admin screens.
Basically I'm expected to do everything from setting up and managing linux servers, security, install and configure software, set up oracle and postgres databases, do DDL and DML work, write server-side code, write web services, create images and do layout work, write test cases, write html, js, css, and know a bunch of JS libraries like vue, vuex, vue-router, webpack, jest, bluebird, lodash, async, tailwind, scss, etc. ad naseum.
