Deloitte Cloud AWS DevOps Engineer interview questions

I was interviewed by Deloitte team for 3 rounds it went like almost 20 days, they have sent email for documents upload and form filling. I have submitted and after 4 days of docs submission, HR called congratulated and negotiating on salary they were like we can offer you max of my current salary . I have clearly told them while processing my profile my current and Expected CTC.. after all done they screwing candidate’s like this don’t think shame Deloitte? It’s time waste from both sides.. on top of that they held one interview on weekend also and saying as they have urgent requirements. Never ever appear of Deloitte interview unless job is important to you .. Worst TAG team , HR team
