SQL Question 2: Find the Average Number of Devices Managed Per Employee at Jamf.
As an IT service management company, Jamf manages devices for its clients. The database contains a table and an table. Each device has a unique and is assigned to an employee via an . The table lists each employees unique .
Given the tables below, determine the average number of devices each employee manages at Jamf.
First, this SQL query will create a subquery that counts how many devices each employee manages and groups devices by each. Then it calculates the of the across all employees. The table still has employees who aren’t in charge of any devices, so those people will be used to figure out the average; their scores will be set to 0.
You can practice a very similar question by answering this interactive Amazon Compressed Mean Question, which is like the one you’d use to find the average, or this Microsoft Teams Power Users Question, which is like the one you’d use to give people resources.
9 Jamf SQL Interview Questions
Jamf is a software company that develops solutions for Apple enterprise management. Youre given access to a table with daily product activation data. Your task is to write a query that calculates the average monthly active licenses, per product_id.
Assume the table structure as follows:
| activation_date | product_id | active_licenses |
|---|---|---|
| 01/01/2022 00:00:00 | 1001 | 10 |
| 01/02/2022 00:00:00 | 1001 | 20 |
| 01/03/2022 00:00:00 | 1002 | 15 |
| 02/01/2022 00:00:00 | 1001 | 25 |
| 02/02/2022 00:00:00 | 1002 | 30 |
| 02/03/2022 00:00:00 | 1001 | 35 |
| 03/01/2022 00:00:00 | 1002 | 40 |
| 03/02/2022 00:00:00 | 1001 | 45 |
| 03/03/2022 00:00:00 | 1002 | 50 |
In this query, we use a window function to calculate the monthly average. We partition by product_id and use date_trunc to get monthly data. The ORDER BY in the OVER clause will sort the aggregation result by month. Finally, we order the whole result set by month and product_id for readability.
Please note that the date_trunc function is specific to PostgreSQL and some other SQL dialects. It may not be available or may have different syntax in other SQL dialects.
