I was hired by professional connections within my field of research. This is generally the norm for someone starting their academic research career after a PhD. Most of the interview process with my day-to-day coworkers was scientific in nature, and the more bureaucratic aspects of my hiring was handled by a recruiter.

The experience is always intense for a postdoctoral position, and I interviewed multiple labs for an entire day. I had to give a research talk, interview with professors, as well as meet possible lab coworkers. Interview extended into an evening meal.
