Having spent most of my career in various startups, I was not sure what I was getting myself into when I joined Yahoo!. To my amazement, what I discovered here was not so different from a startup. The Hadoop team at Yahoo! is filled with extremely smart, hard-working people, who care deeply about their job, Yahoo!, and Open Source. The team moves as fast as any startup does, even though the scale of the problems it solves would make any startup founder deeply envious.

The best part of being the a part of the Hadoop team at Yahoo! is that despite the current global economic situation this team is growing fast! This is not surprising - all of Yahoo! batch data processing is moving to Hadoop, and we need many more great people on to join this team.
