Bloomberg Software Developer (C++) interview questions

My first round was the phone interview. It lasted for 55 mins. Asked questions ranging from C/C++, Data Structures and Algorithms. Also asked me to write a function to find the height of a tree. I guess, I did quite well on it. Got a call for an in-house interview the next day. I had a 2-on-1 technical interview. I thought the interview was tough. The questions were not common and required a solid background in C++ which I dont have. The two interviewers seemed pretty satisfied at the end. They asked me to wait for another interview. But then the HR came over and told me that we were done for the day. I dont know if that means a reject or that means that the second interviewer was not available? Waiting for a reply.
