The interview was approx 70 minutes long, including a 10 minute exam at the beginning which involved identifying around 30 different plant and animal species according to photographs. I travelled for 6 hours to get to the interview and despite getting positive feedback at the time I never heard from the company again. Regardless of getting a job offer or not I believe a rejection email at least should be sent to all participants, particularly when at the final stages of interviews. I was very disappointed with how the company dealt with this.
