Most of the interview was a presentation which I was told to make 20-25 minutes. I was a little unsure on doing the task but did my best as they said they were more looking for our thought process. I was interrupted constantly while doing the presentation by one interviewer and at one point straight up told that was I was saying was wrong which left me shaken desperately trying to finish my presentation. Then because of the constant interruptions I was now well over time and was being told to hurry up because they had another meeting to get to. I knew my presentation wasn't perfect and would've gladly taken constructive criticism after I had finished the presentation. Quite frankly I thought it was appalling interview etiquette to interrupt so much (at all really). They also took a very long to get back to me. I knew I hadn't got the position and had long since assumed they simply could not be bothered to send me a rejection email with feedback.
