Automated Systems interview questions

Two senior management asking about your pass working experience, technical challenges solving. Nice and friendly. Did not go deep in technical knowledge. Seems they are looking for person for facing costumers.

They first ask for your self instroduction. Then ask technical question about Java and Database handling. They asked a lot of Java concept question and methodology on solving query optimisation. They have share a little detail on the job duty but not in detail or in specifics.
