The Kandio Method

Kandio's assessment tests let you assess the candidates, employees, agencies or freelancers you have concerning any SQL task you might have.

Remember that Kandio offers guidelines on which programmers to proceed with, and which ones to discard. Kandio will give you reliable directions about things programmers should know about, but a programmer can be excellent, even if he does not know about all of these things.

We suggest that you use our tests before your interview process to know which ones actually to talk to. The final Kandio report should be a piece of conversation with the strong candidates, rather than a disqualifying process in a late stage interview process.

The test and how it’s structured

SQL is a query language that was first acknowledged as the standard by the ANSI or the American National Standards Institute for or managing data stored in RDBMS or Relational Database Management systems. Its importance mainly resides on the organizing and structuring of data, speedy storage and access to it.

The ANSI Format of SQL is a foundational query language in that a lot of the more recent ones have been influenced by it.

Spread across 15 questions, this test will determine the competency of the candidate in ANSI (SQL Format).

We believe that this setup is one of the most reliable and thorough assessments out on the market, and our SQL experts are continually keeping up to date with the evolution of the language to keep the test up to date.

Which areas (chapters) will be covered in the test, and why was it chosen that way?
