NavSav interview questions

I had a three part interview one with HR one with the director, one with the President. After my interview with the director, he calls and lets me know that he really wanted me for the job, I just have to talk to the president and it'll just be a few questions. The president reaches out to me trying to interview the same day I scheduled for the same day then we have a 45 minute interview. A week and a half later they reached out to me and let me know, I don't have enough skills for them.
