 """ Deletes a list of ``Job``\ s by filter. Example: Args: parent (str):
 Required. The resource name of the project under which the job is created. The format is "projects/{project\_id}", for example, "projects/api-test-project". filter_ (str):
 Required. The filter string specifies the jobs to be deleted. Supported operator: =, AND The fields eligible for filtering are: - ``companyName`` (Required) - ``requisitionId`` (Required) Sample Query: companyName = "projects/api-test-project/companies/123" AND requisitionId = "req-1" retry (Optional[google.api_core.retry.Retry]):
 A retry object used to retry requests. If ``None`` is specified, requests will not be retried. timeout (Optional[float]):
 The amount of time, in seconds, to wait for the request to complete. Note that if ``retry`` is specified, the timeout applies to each individual attempt. metadata (Optional[Sequence[Tuple[str, str]]]):
 Additional metadata that is provided to the method. Raises: google.api_core.exceptions.GoogleAPICallError: If the request failed for any reason. google.api_core.exceptions.RetryError: If the request failed due to a retryable error and retry attempts failed. ValueError: If the parameters are invalid. """
