Delta Air Lines Ramp Agent Ready Reserve interview questions

I applied at Orlando MCO in october. did my hirevue video. about a week later received a letter for a F2F interview. I did my F2F interview and everything seemed great. They told me I did very well as I implemented the STAR method very good. They kept repeating how good I had done in the interview. They told me to expect a call from the hiring manager soon. 2 months later and nothing. My status still says Current- Under review. They did say they would not be selecting anyone that same day. What could have possibly happen? im tired of waiting.
