Hello guys!
I was wondering if anyone could give a heads up or maybe show me a partial solution to this question.
Below you will find a task and an attachment of the dataset.
Task:
The provided dataset (in attachment) lists employee information including their employee ID as well as the ID of their manager. Every employee has a manager except the CEO whose manager ID value is null. HR wants to understand the reporting structure hierarchy within the company. How many employees have 3 reporting levels between themselves and the CEO not including their own level and that of the CEO?
Kind regards,
Alexander
