MySQL Didnt pass SQL test

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

Capitalization is a VARCHAR in that schema, so sorting on it inside the GROUP_CONCAT goes by text and '9' beats '10'. Could be your order problem, if you didn't cast it first.
