Interview Prompt
Given a list of sales records (each a dict with 'employee_id', 'month', 'sales_amount'), return a list of per-employee dicts. Each dict has 'employee_id' plus keys named after each month (as seen in the input) holding the total sales for that month for that employee. Employees are sorted alphabetically by employee_id.
Summary
Every salesperson has a story. The months just tell it sideways.
