AstraZeneca Data Science interview questions

One HR chat, one phone interview, one video interview. The HR chat was normal. The phone interview was quite bad. I got 15 minutes lecture on chemistry, while the interviewer clearly knows I don't know anything about chemistry. The video interview was quite bad as well. One interviewer liked R, and the other likes Python. I can feel the tense between them through the screen. The Python guy is the rudest interviewer I've ever met. He asked questions and expect answer straight away and left no time for the other interviewer at all. It feels like a silly challenge rather than an intellectual conversation. He also half lied down throughout the process. He's knowledgeable but he also have a lot of gaps in his knowledge pool. He seems alright with the things he doesn't know. The R guy didn't get much chance to ask things. I think the interviews represented part of the culture in AZ.

Phone interview by hiring manager. Called me about 30 minutes late. Talks very fast, I can barely catch up. Mostly technical questions. I put all my time preparing HR type questions. Replied a week later, no offer.
