Dyson Engineering Design Intern interview questions

Very unprofessional. Hirevue process was fine. After Hirevue process, they got back to me about a week or two after asking for an in-person interview the following morning. After accepting the invite and confirming the meeting, they cancelled and asked to delay for the end of that week. Then the night before the rescheduled interview, they cancelled the interview process altogether and that they're looking at other candidates and would let me know in a week or two if they want to interview me again.
