Interview Prompt
The data platform team is grading batch job throughput for their quarterly review, where a job's grade comes from the total rows it processed. Jobs tier as 'Outstanding', 'Satisfactory', 'Unsatisfactory' or 'Poor' at cutoffs of 700, 350 and 200 million rows; show each job's name, its total rows processed, and its tier.
Summary
Every batch job gets a grade.
