Reproducing the Issue
Try to post the update query to complete the Overall assessment of the candidate .
For Eg :
<d:message>User doesn't have permission to save/write assessment. for Key InterviewOverallAssessment/interviewOverallAssessmentId=7982 with the index 0</d:message>
This is the Permission issue
The API username you are using to execute the query should be the Interviewer for the candidate .
Eventhough you had granted Full ODATA permission to update all the Entities via API to a particular username, And if the person is not the interviewer the Update query fails with the above mentioned error.
