> - What is DB indexing

Yeah I asked exactly same question, And instead of answering what it i, candidtate told me why they used it.

> - Can you think of any impact when indexing in this situation

That's Why I want to know if candidate understand what really index does, One cant tell a realistic answer of this question until S(h)e knows how index works.

> - What are you general thoughts about indexing, can you think of an example when you used it and how it helped.

Even if one used it in some situation in pastm and it helped, I would consider it not enough as it could be possible S(h)e used it by reading some blog/tutorial etc without understanding it fully, it's like ok switch it off and on, did it work? well forget about it then.
