It's not possible for us to tell if you'll be the interviewer or the interviewee. 😉

A lot of people as for questions to help them prep for interviews for jobs that they're not actually qualified to do. It's given me a bit of a jaundice eye when people ask such questions as you did... especially when they also want the answers to the questions.

I've not made such a search for questions of the nature you ask but a look at "Yabingooglehoo" for the following should be a help.

If you look at "SQL questions and answers medical databases" on Google and look at the "pull down" for other subjects, you should get a snoot full of what to look for. You might also want to do a search for "SQL HIPPA COMPLIANCE".

One point, since there are a large quantity of completely different databases that store healthcare information, you are unlikely to find a generic list of "SQL queries" that will apply to the specific database you're using. It's very likely that you'll need to learn that database and write (or track down, it is possible) queries for that database, not simply "healthcare databases". There are far too many of them and they are absolutely not standardized (despite HIPAA).
