d) SQL - The tech lead should be familiar with SQL development and be able to write queries to join/union/unload/copy/insert data without needing to reference many if any documentation
Referring to documentation for syntax with a SQL database you are not familiar with is fine, needing documentation on the types of joins and how they work is unacceptable.

6) Security
A) A tech lead is responsible for ensuring data brought into our database is secured properly according to business rules.
