2 interview process. First one was a phone and super casual with typical "why do you want to work here questions". The second one is formal with the prospective manager. They are very friendly and make you comfortable during the interview and even mention what they're looking for in answers.

I was hired through talent acquisition, messaged via Linkedin, then spoke on the phone for a phone screening (very brief) just information on the program and Hilti. Had another phone screen with the department head, where I spoke on the phone about myself. Had a skype interview with 2 people, (the dept head, and another Engineer). Wasn't hard, they are looking for individuals that have personality, not robotic engineers.
