The recruiter asks you basic questions. Then you have a one-on-one with a peer, which includes some technical questions. The last part requires interviewing against a panel of their best.

Extremely difficult technical questions really test your knowledge of best practices and how to get the best performance out of the language. I am sure it is pretty important that you are a positive thinker, too, and seem like someone who doesn't get frustrated by challenges.

Basically, I was asked how to set up a specific database based on specific parameters.
