Indeed. I've had a bunch of jobs, and my experience has been that the job interview sort of reflects the people and structure / organization you'll be working with.

To put it this way: The best places I've worked at also had good interview rounds, while some of my least enjoyable employers had less enjoyable interview rounds. The absolute worst interviews have been at places I didn't get an offer, or I didn't pursue afterwards.

If the person interviewing me is rude, glued to their phone, uninterested, and in general indifferent to what happens - I'm going to assume that's a reflection of how the company culture is. I can also understand that not all people tasked with interviews will bring their A game every time, and that there may be external factors at play - but those places usually show a pattern.

I've yet to interview at a place where the interview was terrible all around, and then find out that the company is gold.
