I applied at an internship for the position of a Junior Java Developer in Test and I am wondering if you can provide me some screening question examples?

The internship requires that I have strong knowledge in SQL and Java. I asked the recruiter to elaborate on the technical interview questions and she responded by telling me, how would you test X.

I am confident in my Java skills but practicing examples can never hurt.

Why not get a simple Java database like h2 at h2database.com and build a database of your media like books, cps and dads and then play with the sql to query and maintain it.

In sql you'll need to know CREATE TABLE and SELECT with SELECT being used far more often.
