What sample code is appropriate when looking for a job?
If you have tests, great. Take out one module of your app and if necessary, add some more comments and check if indentation is correct.
I as an employer would be interested in the coding style, the quality of the comments ("comment why not what"), if the style is used consequently (so that if you have seen and understood one module of the app, the next module following the same coding guidelines is easier to understand). If you're using external modules for some parts, good; if you are not using a module that seems to fit at a first glance, then comment why you are not using it.
