The email exchanges were normal, polite etc. It was the in person interview that I literally wanted to walk out of. The person interviewing me told me "you use too many filler words, like "umm" and "like". I just wanted to let you know to try to use those less when you meet with her because she doesn't like that". At that moment she went to get the CPO and I already knew I didn't want to work here. Fortunately the CPO couldn't meet me on that day and I drafted my withdrawal email on my way back to the train.
