+Note: Softskills are not about asking, how someone does a code review, how well someone understand Scrum, or how someones tests code. Softskills are about behavior and communication. Therefore these topics are separated in way of working and personal assessment. Any you see, way of working is sorted under technical assessment.

 Expected answer: There is really no expected answer here. This questions is to check the candidates knowledge, understanding and depth of sql. A high tier answer would be something like:
 I'll index the createdAt column in the table
 then I'll query and sort by createdAt desc , selecting only rows from previous 7 days
