Was very thorough- it was about a 3-4 interview process with typical interview questions and also some scenario based questions. Included shadowing the position before receiving an offer which was nice

Applied online, and got an email from the PI cc'ing other people from their department. They gave a specific time asking if they can call at that time, when I replied yes, the PI shared their phone number and asked me to text them when I get a chance and they "will try to call". They called later that evening 8 minutes late of originally assigned time. When I picked up the phone they did not even bother to ask any "how are you". They asked "what do you want, what have you done?" When I started answering they interrupted me, and started scolding! And it continued for the whole interview, I was not able to answer any question, they interrupted me every time and started scolding. My view point is if you do not think I am a suitable person for your post, why bother calling me and not hearing what I have to say?
