I signed up, and the presentation should be a few days later. One or two days later, Oracle called my home and asked to speak with me. It was what my background was, and I told I enjoyed programming and told them my age, explaining I was still going to school.
They said that unfortunately, the event was for grow-ups and that I couldn't attend it. But no worries, when it did an event for kids, they would call me.
Thankfully they never called me back. Now I'm a happy PostgreSQL user and only queried an Oracle database a few times during my bachelor in Computer Sciences because the teacher of database systems forced us to use it.
