I have recently completed my Amazon online assessment tests for SDE new grads. I have scored pretty well in OA1(7/7) and OA2(2/2) which passed all the test cases and also in OA3. After 5 days my application status in the job portal changed from 'Under Review' to 'Application submitted'. Has anyone faced this issue, I was not sure why this happened. Does this mean it's a reject?
