Lumen Java Developer interview questions

I went for interview through a staffing consultancy and interview took 1 day. They told to come at 10 AM and had to wait for 2 hrs to take up first round of interview and no respect from hr panels never attend from staffing consultancy. First Round was Technical and Programming Writing Test for 45 min. Second Round was Face to Face and was asked question with respect to your project, collections, Strings, Hibernate, Spring , Maven , Singleton pattern. It went for 45 min answered all questions round But there was no reason why they told i didn't select and told didn't clear leave for the day.
