Recently, I asked our job candidates the following dummy question:
Could you comment on some new features of ORACLE 8i in comparison to Oracle 7?
Answer one: Eh, Eh, .... There are a lot of new features in ORACLE 8i. I don't think there are a lot of people who are using these new features...Most companies just use Oracle 8i's relational database component..... The big difference is that Oracle 8i is object-oriented, but few companies really use object-orientned database.
Answer two: Indeed, there are a lot of new features introduced in Oracle 8 i. So far, I have just got the opportunity to use one of these new features. In Oracle 8i, one can drop a field in a table. Recently, we got some flaws in the database design. To adjust our database schema, we copied one field from one table to another and then dropped the original field by using this new feature.
The candidate who presented the second answer will join our team next Monday. His answer is very professional and he succeeded in walking the interviewer into some small corner. If we think about it carefully, he has not answer the question completely. His strategy was to transfer interviwer's attention and make them forget about their original question.
The first answer was presented by a guy with 10 years of experiences. Maybe he thought he would be a perfect fit in our team. He was very talkative and I had an impression he was trying to demonstrate he is a superstar. Unfortunately, his random remarks severely irritated our DBA so we decided not to push him.
If we are hunting for a job, be sure not to be a big mouth. For instance, some job candidates told me that "Websphere is stupid". I immediately got alert though I personally do not like Websphere.
