From my perspective, I think it shows poor judgment that you've chosen hardware where you can't get your webcam and bluetooth headset to work under Linux. Or you haven't bought a wired headset and a USB webcam that you've researched and know works properly under Linux. It sounds like the alternative you've chosen is to take interviews using an OS and development environment you're not comfortable in, which seems like a foolish choice to make.
These days it's not difficult to buy hardware with Linux in mind, even on a budget. (And if you have two computers, I feel like budget is probably not really a problem for you.)
