After 3 rounds of interview's I was told that I would be advancing to the next step of the process which would require an in person interview. 1 day before my scheduled interview I was told the the deputy director had an emergency and would be out of office for 2 weeks and that they would contact me to reschedule. 2 weeks later and still no response, I decided to reach out to follow up in which I received a response saying that the role had been filled. Professionalism is free, please be mindful of the time you are taking from candidates only to not follow up.
