Mounting VirtualBox shared folders on Ubuntu Server 18.04 LTS (Bionic Beaver)

This guide will walk you through the steps on how to setup a VirtualBox shared folder inside your Ubuntu Server guest.

Prerequisites

This guide assumes that you are using the following setup:

• Oracle VM VirtualBox version 6.0.10 with Extension Pack installed
• Microsoft Windows 7 SP1 as the host OS
• A fresh install of Ubuntu Server 18.04.2 LTS as the guest OS

You could still make this guide work with other setups (possibly with some modifications to the commands and whatnot).

A lot of these are outright stolen from Edward O'Campo-Gooding's list of questions. I really like his list.

I'm having some trouble paring this down to a manageable list of questions -- I realistically want to know all of these things before starting to work at a company, but it's a lot to ask all at once. My current game plan is to pick 6 before an interview and ask those.

I'd love comments and suggestions about any of these.

I've found questions like "do you have smart people? Can I learn a lot at your company?" to be basically totally useless -- everybody will say "yeah, definitely!" and it's hard to learn anything from them. So I'm trying to make all of these questions pretty concrete -- if a team doesn't have an issue tracker, they don't have an issue tracker.

I'm also mostly not asking about principles, but the way things are -- not "do you think code review is important?", but "Does all code get reviewed?".
