I was initially selected through Amdocs AMCAT test. They had advertised it on AMCAT and on other job hunting forums. It was basic AMCAT test with computer coding module added. Personality checking through questions, English comprehension test, Logical reasoning and Quantitative aptitude were also checked through that test. I was intimated that I passed that round through a phone call some days later. Also, a mail was sent with the specific request to print it and bring it as some kind of a pass. The interview was fairly a one on one type with two senior employees checking my coding, technical concepts and my resume. That was the first round. The second round was more difficult with another technical round asking us to code according to the conditions given by them. They did not ask any testing questions as such but were only checking whether the basics are well understood. They are asking purely based on the skills mentioned by you in your resume, therefore please be sure of what you are mentioning in your details.

First round is HR screening call, second round will be technical where you will be asked for questions related to your current role and some technical questions and last will be managerial round. Overall just read the job description and prepare accordingly.
