Snap-on Java Developer interview questions

I was interviewed at Snap on--Aug 18, The first Round was telephonic as i requested to the recruiter, in telephonic the person asked only 2 question related to Core Java, second round was F2F, Recruiter called for interview but their behavior was very Rude and interviewer asked me again 2 question and rejected me, I just want to ask these people why you people called candidate for F2F interviews when you are not interested in them, Dont waste your time and candidate's time, Be professional and Stick to your requirement which you need. Hopeless people and worst interview Experience, Snap On Noida People are not professional.
