That was my experience every other time I've applied to a job in the last 10 years, but not during my recent job search. I got a number of rejections from 5 minute first round interviews for no obvious reason. Whereas once I got to a "proper" interview it was plain sailing. I think companies are getting a lot more applications than they were and are having to put a stronger filter in the first rounds than was the previous norm.
