Software Engineering

"Make everything as simple as possible, but not simpler."

- Albert Einstein

Writing software is a messy business - You are tasked with coming up with a solution that works. This is probably best exemplified by the Netflix Prize competition (see wikipedia article for a quick overview if you have not heard of it before).

One consensus I got at KDD Cup 2007 was a slight disappointment at the "hackish" nature of the leading team, which later won the 2007 progress prize. Their winning solution is described here.

It is easy to have bloat creep into code as bugs are fixed and features are added.

One positive plus of working in Google is the inclination to frown on code bloat, and engineers are recognized for coming up with simpler implementations. This philosophy of constant iteration of software engineering ensures that systems are capable of keeping up with features while being maintainable. (Unit testing is HUGE here too)
