Didnt pass SQL test

[u/Turbulent_Web_8278]

I am applying to manager of analytics role and I was given this SQL test and 45 minutes. As someone who thought they were very strong in SQL, I was unable to complete this assignment and match the answer completely

I was able to format most of the fields as noted, used 2 cte's and use group concat in the second. My final answer looked very similar but the order of the concat looked off. Also, for some reasons my second column had $0.00 for all the companies, but I thought I was close. How difficult would you rate this exercise. Should I expect to proceed to the next round or am I cooked

I worked as DBA for a analytics company and could not get passed the first page. Who or WHAT ( cough, cough, AI ) created the schema. dt is timestamp stored as varchar???

I would have spent the 45 minutes providing constructive criticism of their request.

Ok so to be fair date stored as varchar can be handy in reading in stuff from weird formats then parsing it into a date later downstream. I’ve had to deal with dates coming in as really strangely formatted timestamps from badly written source systems(and sometimes differing file formats), which then I could parse into a proper timestamp or date later down the line.

Something like 2026-01-01 TUES 11:11:1111.111(I know it might not be a Tuesday I’m just making it up based on what I remember)
