A good personal open source project is worth more when interviewing than anything else really. Can't fake that in an interview.
For example we compile locally, then manually move the compiled code over to the server instead of using something like docker. Part of this is the restrictions we have over our environment, part of this is inertia.
Fortunately I haven't given up trying to move to that paradigm but sometimes I actually dont want to be on a modern team. Its like I have plateaued to a comfortable state that I know wont always be there but I wish it did. I hope what I am explaining makes sense.
