What are the job ids for jobs done more than once for a period of more than 300 days?
SELECT job_id FROM job_history WHERE end_date - start_date > 300 GROUP BY job_id HAVING COUNT(*) >= 2
``` yaml
job_history: # name of dataframe
- EMPLOYEE_ID:
    dtype: int64
    sample_values: 102, 101, 101
- START_DATE:
    dtype: datetime
    sample_values: 1993-01-13, 1989-09-21, 1993-10-28
- END_DATE:
    dtype: datetime
    sample_values: 1998-07-24, 1993-10-27, 1997-03-15

    dtype: string
    sample_values: IT_PROG, AC_ACCOUNT, AC_MGR
