Meta Sr. Software Engineer interview questions

The recruiter gave me a good overview of the interview process and exactly much time I would have to dedicate to studying to make it through. Expectations were set well.

I was solicited for an interview via LynkdIn. I spoke with the recruiter on the phone and subsequently scheduled a bluejeans coding assessment which was conducted by a junior engineer. Although I easily answered both coding questions with an optimal solution, they passed on an on site interview. It was a waste of my time. Why solicit a person for an interview, and then decline to interview them once they ace a coding assessment? Clearly they were not interested in my resume to begin with, but want to have a steady stream of candidates for some sort of numbers game. This further diminishes my opinion of a company which I already held in low regard.
