You've probably heard that Twitter just raised another $200 million from investors. It plans to use much of the money to continue hiring the tech people it needs to keep its services expanding and its user base growing. (By the way, the total amount of money it's raised to date is about $360 million.)

In the past year the company has grown from 130 people to more than 350. Just this week, it acquired Fluther, a question-and-answer site, as a way to get hold of its engineering talent.

Twitter likes to bring on new people by way of acquisitions. But still, the company hires people directly when it finds the right fit. And what kind of people might that be?

Twitter wouldn't return our calls seeking comment. But in a blog post, the company explained:

More than half of our employees work in engineering and operations and those teams continue to grow as we attract more and more talented people interested in the challenges of building a global information network.¿ said a Dec. 21 Twitter blog post.

Twitter views recruiting and views its own employees as some of its best recruiters. If any Twitter employee knows of, or happens to run across a talented person, they can reach out themselves to begin the recruiting process. 

Unlike Google and Facebook, Twitter doesn't say much about what it likes in a candidate's schooling. Instead, it prefers to find people who are passionate about innovating and being part of growing its site.

You can keep with its recruiting activities by following @jointheflock or @TwitterEng.
