Samsung R&D Institute India - Noida Intern interview questions

I was called at a predefined time for the interview. The person who interviewed me seemed knowledgeable in data structures and algorithms. He asked me mainly graph questions and questions about general data stuctures and algorithms. The interviewer also asked me to describe the algorithm to find out if any bridge existed in a given graph. I was also asked if there is any correlation between bridges existing in a graph and cycles existing in a graph.
