Pinnacle Infotech Java Developer interview questions

I got mail from company regarding Opening for Java developer I reach at 10 am but interview started at around 12 ( about 10 to 15 candidate were there) Interview was started with basic java concept like oops ,class , collection framework etc. After cleaning first round there was machine test in we had to create form using JDBC which support all operation like create,read delete and update. I implemented it in JSP but they wanted in java Swing (it was very difficult for fresher). I failed to crack machine test . after that I waited for about 2 hours and they come with special offer that if I have to join company have to pay 25k and if wanted they can provide experience letter . I realised it's fraud and I immediately declined offer.
