Developer turned, presales architect (a "non coder"), have to prep for Hackerrank test on python and SQL.

Hi all, need help... the subject says it all. About me: consultant implementing systems, was a heavy coder writing backend code in SQL and PLSQL, etc. UNIX scripting etc. Now: Interviewing for a Enterprise App company, and will be vetted by hackerrank with 5 questions in 2 hrs. Was an expert at SQL and Unix shell scripting. What should I expect and how do I prep myself. Tips and guidance to make it thru. Thanks.
