The interview went very well, initially I had a phone interview with the hiring manager who then invited me out to Chelmsford, MA for a face to face interview. I had flew in and out in one day and was asked to provide a side presentation at the end of the interview. I had 4 interviews back to back, each about 30 minutes. There were typical questions and it seemed to go very well with very positive feedback. At the conclusion of my presentation, I received very positive feedback and by the next few days I had my references checked and was offered a position. However, I did not accept the position due to lower salary for the location and high travel requirement. Overall a good experience with great managers, I just wish we could have come to an agreement on salary based on travel requirements and my experience.
