Going through a coding interview is not fun. The questions you're asked can come off as pointless - there's a reason you're asked these things, however.
I like building things and sharing my experiences. I've mostly focused on the web, but of late I've moved a bit more towards back-end systems and databases. I also love working with Audio/Video.
I think sharing what you do is incredibly important; equally as important is to make sure you never posture as an expert unless you truly are.
