SPS Commerce Senior Business Development interview questions

The interviews were pretty standard in the beginning. HR screening call. Then had two 1-hour interviews with senior members of the team. Interview was very application-based and "how did you approach" or "how did you approach" situations. Then more rounds of interviews with other folk around the business. After several hours and weeks of (what I thought were positive) interviews, I was hit with a generic automated rejection email. I found it insulting and unprofessional.
