Bloomberg Software Engineer interview questions

Had a phone interview with a developer about a week after applying. The questions were pretty standard, mostly about very technical details of C++. After that I got two easy coding questions (1. what is the output of the following code, 2. implement an easy function). The interviewer didn't give any signs of expecting other or more detailed answers and generally seemed to be satisfied. He told me I would get a feedback in a week. Two days later I saw on Bloomberg's job site that the status of my application was changed to No Longer Being Considered but I didn't get any emails about this (not even an automated one). I sent a polite email to the recruiter asking if she could share any information about why my application has been rejected and got no answers at all. Not providing any details about the reasons of the rejection is something I don't like but I can accept. But never contacting a candidate again after a phone interview just feels unprofessional.
