I have tried to use but it does not bring me the desired results

SELECT DEPARMENT
    , MAX(JOB)
    , COUNT(QUARTER)
FROM TESTHIRED_EMPLOYEE
GROUP BY DEPARMENT
    , JOB
    , QUARTER

To obtain a table like this

DEPARMENT	JOB	Q1	Q2	Q3	Q4
Support	Account Coordinator	30	0	10	5
Services	Account Representative III	0	2	3	1
Research and Development	Account Representative III		0	0	12
Business Development	Account Representative III	10	0	0	2
Support	Account Representative III	23	2	1	6

This documentation should explain a bit: https://learn.microsoft.com/en-us/azure/databricks/sql/language-manual/sql-ref-syntax-qry-select-pivot. It also has solutions without a pivot with the use of, in your case, count(qarter) filter(where quarter = 'Q1') as Q1
