San Francisco Symphony interview questions

A telephone screen with HR followed relatively soon after by an in-person interview with the hiring manager and an underling. Both went well, and I was given nothing but favorable feedback by all parties. I was told a decision would be made by the end of May 2017. When I hadn't heard anything by early June 2017, I followed up in writing. No response. Nothing. Crickets chirping. Disappointed by this, I came to this site to see if this is common. Having read the reviews now, I am realizing there are major, ongoing, systemic people problems at the SF Symphony. I still haven't heard back from anyone there, so I am assuming I never will. It is very rude, unprofessional, inconsiderate treatment, but I see now that I have probably dodged a bullet. I wish I hadn't wasted my time and effort in the first place, though.

I was referred by a current employee. The interview process included a phone screening with the HR rep, plus 4 different in-person interviews with hiring manager and other members of the department.
