Applied on campus from career fair, then got a phone interview shortly afterwards. First a bit of behavioral stuff, i.e. resume (projects, classes) and why MongoDB. Then was asked about basics of Python, like list comprehensions, threading, etc. Afterwards I was asked a simple technical question involving pointers (I think something about squaring each element in an array and having the order maintained). Wasn't too prepared for the language details so I messed up a couple of those questions.
