Capital School interview questions

I was approached by the HR of Capital school, they discussed the job role and salary. My information was then forwarded to the other HR and got a call from them to arrange an interview with the Finance dept. I agreed for the interview and was told that I will get a call the next day. Low and behold, I waited for their call for many days and never got one. I messaged them with gentle reminder about the interview but they left me on seen. If that wasnt frustrating enough, the other HR who approached me earlier, blocked me with no explanation at all! Worst experience of ghosting ever from a recruiter who approached me first. Very unprofessional behavior from the HR team at Capital school
