Age old process of lobbying the candidates and pooling them into a meeting room and making them wait and sending them in to the meeting room one by one. These people, even if you digitize and streamline everything , they'll still make you wait and waste your time. I had interview scheduled at 9:30am and, i joined in time, people who joined pretty late entered but i was still there for 1 full hour just to be sent into the interview room. The interviewers were far from being professional, started with introduce yourself and then boom, we'll get back to you. What the heck could you judge from the introduction? An hour waiting for 1 hour for a 5 minute call. This is lazy mindset of the host and nothing else.
