I was on the stability and security team. My internship was centered around ZooKeeper mostly, but I had a lot of freedom in choosing the direction that I take the project. I was given the option to change projects and even teams in the middle of my internship if I wanted to try something else. The work-life balance was the best that I have seen and people often stayed after work to play games or hang out. Even though I was the only intern for a part of the time I was there, everyone made me feel very welcome and treated me as a full-time employee. They even let me shadow couple interviews and ask a question on one. I still keep in touch with the people on my team and visit the office whenever I am in town.
