&gt; I think at Google&#x27;s scale one of the biggest pain points is almost certainly integrating new employees to do things &quot;the Google way&quot;.<p>Ramping up at Google is definitely a stressful process, but I don&#x27;t think open sourcing technology puts much of a dent in that. Even if you show up your first day at work knowing every tool Google uses, on your second day there will be some new tool and something else will be deprecated. By a couple of years, damn near every piece of software you were familiar with will have been replaced by something different. You are in a constant state of learning.<p>This is, I think, one of the reasons Google places such a premium on algorithms and data structures in hiring. They are some of the few things that don&#x27;t change often and being familiar with fundamental concepts makes it much easier to quickly pick up a new tool that uses them.
