In this article I will cover telephone interview phase of recruitment process which is generally performed after receiving CV and before face to face (or video) interview. This is a critical step and I suggest to always do it and if the candidate is successful follow up with more comprehensive test.
This article will provide a set of questions that will cover SQL Telephone Interview Questions and I will provide answers. I will provide the sets in different categories and they will represent my understanding of certain 'level' so feel free to mix & match and I strongly recommend to include your own questions that are more relevant to the role you are recruiting for.
