The entire process was very quick. I submitted an online application for a recently posted position and within 2-3 days I was offered an on-site interview the following day (I live close by). I interviewed with two people: someone I would be working under, and a "younger engineer", one by one. Most questions were behavioral. All of the technical questions either related to my past experience, or asked me to draw parallels between the responsibilities of the position I was applying for and my past experience. One of the interviewers gave me continual opportunities to ask questions. I thought of a lot of very specific questions in advance, and had them written down where I could slyly look at them, which was helpful. The other interview was a very direct questions-answer interview, and was less conversational. The most difficult thing was to ensure I could answer quickly, so it didn't feel awkward. Having gone through lots of difficult STAR interview questions online was very helpful, because I had good examples ready for most questions.
