What do you consider to be the most difficult case or project you have worked on during your career?
With this question, your interviewer is not just looking to hear what you felt was the most difficult case or project you have worked on during your career to this point. While you should do a good job of painting the picture of what the case entailed, spend as much time as possible in explaining your process for helping facilitate the best outcome possible and the steps you took to get there. Prepare an answer that keep the process as much in mind as the end goal for this question.
"Last year I worked on a patent infringement case where we were attempting to prove that the infringement was willful. After reviewing all of the case details with my client's executive, R&D and sales teams, I thought we had a case in that the infringing companies lead R&D Scientist had been formally employed by my client. I assembled a team from the client to help pull any communications and meeting notes that the competing scientist would have been a part of. The planning stage of the product in question had started almost eight years prior and the scientist had left employment six year prior, so there was a two year window that they would have been digging from. With my advice on when to dig and what to look for, the substantial record keeping of a couple of individuals helped prove our case of willful infringement and was a huge win for my client."
