I have had to fly and stay multiple days overnight in New York City, Minneapolis, and Atlanta for job interview processes in the past. This was absolutely the norm. What's not normal is a couple relatively brief online transactions (2-3 Zoom interviews, a work sample test) clinching a job. That's quite new.
If anything the hiring practices have gotten much shorter.
I’ve had the _Batesvilke Casket Company_ in _Batesville Indiana_ demand I come in for multi-day interviews.
