Very straightforward and kind. Hiring managers are as human as they can get. Questions are not awkward and are easy to answer. Punctual and informative. In my case, there were three interviews in total.
A short test to see your response in certain situations, followed by a 30-minute interview after review. You had about a week to respond to the email with your answers, which was plenty of time, and then you were allowed to choose your interview date and time.
