Well, you will kind of be tested on everything. I didn't even apply for the algorithmic/coding position of Software Engineering, but for Forward Deployed Engineering, for which you still have to be an engineer, code, and know your stuff very well, but you at least don't need the algorithmic knowledge of a TopCoder champion like you probably do for Software Engineering.

Whatever technical position you apply for, you definitely will be tested on systems, coding, and algorithms though.
