Amdocs Applications Support Engineer interview questions

I have cleared all the rounds, already submitted documents, waited for 3 months for offer letter, after asking update on every week. I got a mail from Amdocs that We won’t be able to consider your candidature for now, will get back to you if anything comes in future. Seriously worst experience ever. Note : if you will ask for any update to HR team they will only say one word to you. "We will get back to you"
