Meraki Sales Operations Analyst interview questions

The process took about a month. I had a initial phone screen and then spoke to the hiring manager over the phone and in face to face... So I was brought on site to the office and during the interview process the recruitor told me that one of the girls that i was interviewing with is planning to leave the company and now the position that i am interviewing no longer exist. This made me extremely upset that fact that I wasted my time to interview for job that does not exist any longer. Also felt the people Interviewed with seem a little imature.
