Procter & Gamble Process and Engineer interview questions

First you fill the application on the company site, then I done the online and offline test on Jan 2018 after the 2 months I received an email that I passed the test but the vacancy is closed. I applied for another vacancy after 6 months, I had 2 interviews at Cairo plant on the first week of October after applying with about 3 months, I received rejection mail after a week from the interview then after another week I received a phone call to come to a third interview the day after and that the rejection mail is a system error. After the third interview with 3 months my application status changed to offer accepted on the website without receiving any phone call, I call the call center he called me it's a system error again and we will check. 5 days later the status changed to final interview completed and then a rejection mail was sent. worst experience I have ever had a lot of errors, very long time and no one could give you when it ends or what's your destination, all the answers is just wait.
