how to assess a sql expert for a job?

  • Hi, I need to create a job description for a SQL developer. My company has several applications which use stored procs so we're going to hire a SQL guy so we can offload all SQL work to a single specialist. That being said, how would you write a job description for this? What sort of bullet points would you put in the JD? I'm decent at SQL but not a specialist. I wouldn't be qualified to interview a SQL specialist because I'm more of a full stack developer.

    Some things that might be helpful might be 5+ years of BI, Data Warehousing and Reporting. Could you be any more specific than this? Are there any specific technical concepts that would make sense as bullet points? What about things like 10+ table join queries? What sort of interview questions would ask and how would you assess a candidates qualities and abilities for this role?

  • Search the forums for 'interview questions' or 'interviewing'.'

    I know I've seen several discussions of this over the years.

    Step 1 would be to identify what you want such a person to actually do. You say you want an "SQL Developer" and then you list BI, Data Warehousing, and Reporting. That's more of a "BI" guy.

    SQL Server has a huge number of facets. You need to decide what you want your "SQL Guy" to actually do.

    ________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.

  • The thing to do might be to hire a consultant to do the job description and the interviews for you. As Jeff says, you've split the difference between a BI person and a database developer. They are two different skill sets and different people will apply to the job depending on which set of skills you describe.

    Assuming you can't get a consultant to help out, I'd start with listing the actual needs in plain language. That might be all you need. However, once you have that list, translate as much of it as seems appropriate to technical language. Something like "I need someone who can create fast procedures to query the database" might translate to "Proven track record with high performance T-SQL queries."
