Open Society Foundations Program Assistant interview questions

I've applied for two positions at OSF - one in the summer 2015 and one in the summer 2016. Both times the way the application process was organised was terrible. The first time I did not get an email confirmation after I submitted my application so I emailed an HR person to check if they've received my application ok. No response. I understand that everyone is busy but isn't it part of the responsibility of an HR person to reply to enquiries like these? I never got a rejection or acknowledgement I ever applied to the position. The next time I applied I received a confirmation of my application but no information thereafter. No rejection even months later. At this point I am not going to bother ever applying again.
