Initial communications: Cold call by future employee, followed by emailing resume. Led to in-person interview same week.
One in-person interview, lasted 1 hour, led to tour of office and offer same day, official offer letter following day.
Interviewed by two principal engineers, both were genial and welcoming. Little technical examination was needed; interview mostly consisted of determination of the type of personality they prefer (good communications skills and openness). Very friendly and slightly on the informal side.
