Atlassian Senior Technical Support Engineer interview questions

Interview was 2 technical and 3 manager round. Initially communicated will be 2 technical and 2 managerial round. Though technical round was good . For manger round Dc on prem taken by 2 managers was also fine . Later Hr said need to visit office for face to fa e round . With no proper justification i had gut feeling on this that they will eliminate as they are looking to eliminate and need reason, and same happened gave interbiew face to face to shafath and was rejected with mo proper justification from Hr . You spend hrs of skill to and when getting rejected by manager that too 1 manager of same skills is complete waste .
