I was intitially contacted by a project manager. After a number of phone interviews, I met in person with the project manager. Following that, I was brought into the office to meet other project managers that I would be working with. After another two weeks, I was extended an offer.

Interview was quite amicable, probably helped that I was recruited from one of the feeder engineering programs for Carollo. That was over a decade ago but then, a fair number of the senior partners were graduates of my engineering program. I was interviewed by two senior partners (individually) and then went from office to office speaking with about 4 or 5 engineers at different levels of the company.
