ADP Member Technical interview questions

I attended this company interview process through institute. It has 4 rounds 1. written 2. TR 3. TR 4. HR written test is very easy to clear as it consists of aptitude, reasoning, english and programming questions. 1st technical round was very easy about my project. 2nd technical round was little tough (all about collection framework, advanced java). didn't clear 2nd TR.

i have attended a pool campus drive first round was technical some simple questions next was tr asked simple questions and programs but unfortunately i was not selected because they required only 5 to 10 out of nearly 800 so rejected in technical
