Synopsys Senior R and D Engineer interview questions

The interview was very comprehensive. I interviewed by 7 people including HR. Before the on-site interview there was a screening interview on the phone. The questions were related to the knowledge of the area/field as well as software engineering, algorithms, problem solving and data structures. The interviewees were very professional and respectful. The questions were not easy. The interviewees were willing to work with me on problems that I didn;t know answers to.I would describe the overall interview process as quite pleasant.
