Great point. All of the interview questions on MSSQLTips.com are intended to serve as a sampling of questions for both sides of the table. They are not intended to be a comprehensive aptitude test nor intended to determine if someone will fit into your team. In many circumstances, different questions would be needed for each candidate to really assess both of those items.
I hope this makes sense.
BTW - If you have questions you would be interested in posting, we would be interested in include them in an existing tip or a new tip. Just let us know.
