So I’m currently applying for a more senior Data Analyst positions and i wanted to know what to expect in terms of SQL interview questions.
what’s the typical style? Is it take home usually? Using a laptop? Or straight up old school annotation on paper?
I’ve kinda looked online and the typical SQL questions i see are for DBA’s or Data Engineers.
I’m self taught in SQL and generally write SQL queries just to get the data out and plumb it to a BI tool.
I rarely consider the efficiency of the query unless it’s super slow.
Any pointers?

I'm pretty sure this a spam post. The exact same question was posted on Reddit a month ago. It's looks like the ol' one question from login and answer with a link by another later on...

https://www.reddit.com/r/SQL/comments/y2up02/typical_sql_interview_questions_for_data_analysts/

My other recommendation is that, if it takes someone a month to figure this out, they're not qualified for the job to begin with! 😀 😀 😀

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

If you are actually a senior level person, one would expect that you should be aware of a typical situation you may have encountered, and what solutions you may have applied. "Data Analysist" can encompass a pretty broad set of skills. If, in one example, a position may require coding in the R language. You are not going to be able to study a cheat sheet and be able to pass the interview.

What do you mean by "style"? Would you be expecting a technical exam? A verbal exam? I think the bulk of the interviews would be describing a situation, problem, and desired outcome. You would be expected to provide what you would to to understand the situation, solve the problem, and achieve the desired solution.

If you make that kind of statement in an interview for a SENIOR level position, expect a lot of rejection.
