There were 2 technical rounds, followed by HR discussion. These rounds took 2 weeks. After the HR discussion, they verified documents and shared the proposed salary structure and told me to wait for offer letter. I waited for one month. I tried to follow up with HR, she only kept me telling we are waiting for global approval etc. After one month, I received automated mail from Atos that the opening has been closed. The HR is not responding as well. This is very unprofessional behaviour by such big organisation, but it's very normal for these companies to waste time and play with candidate's emotions.
