Zillow is growing like crazy, so there are new faces every week. Sometimes it's hard to keep up! And because Zillow is growing so quickly, sometimes the resources can't keep pace. You encounter the occasional growing pain, or what I like to call the 'awkward puppy' moments (you know, when a puppy appears to be quite a big dog but still has huge paws relative to its body size and is a bit clumsy). The expenses system when I first started is a good example, but it's better now. For me, these are insignificant details when it comes to my overall job satisfaction.
