Ericsson Salesforce Developer interview questions

Interview process took more than one week 1st day - 1 technical round cleared 3rd day - 2 technical round cleared 5th day - Managerial round cleared 5th day - Asked for the documents and i submitted the document 8th day - Hiring process is completed and we need two approval we are waiting for it - was the update 9th day - big shock - You haven't cleared 2 nd round interview. If i haven't cleared the 2nd round why you guys took 3rd round and asked for the documents. Shame on you part. Waste of time
