First round started by a call from the senior manager of the team and we discussed the role in 15 minutes, he asked me about my interests and expertise related to the position, them in invited to an on-site interview with a group of engineers. Technical in nature, but also personable. Rotated through a number of engineers and HR to talk about work experience etc. Interviewed onsite and then followed up with the manager at a later date. All steps were professionally friendly.
