Most professional interview experience I ever had. Position was in Rensselaer, NY, and I was going to be home in NY, visiting family. They arranged to get me in, offered to compensate me for the drive up from downstate, NY, and though I didn't get the position, I was notified promptly about their choice to go with another candidate due to their greater experience and background that is directly related to the position and industry. Also, the HR representative gave detailed feedback on my interview, and the comments of the interviewer. Regeneron really set the bar for how a company should treat someone going through the interview process. Even without getting the position, my lasting impression of Regeneron Pharmaceuticals is fantastic.
