I have been interviewing for various FP&A related roles (SFA, FA, Financial Systems) and so far keep getting rejected.

During the interviews (with both hiring managers and recruiters), they seem to be impressed with the projects I worked on and models I created, however, when it comes to asking questions about the role and the company, they seem to be losing that excitement about me, as I keep asking pretty generic Qs (tell me about the culture, tell me about the team, benefits, etc.). After interview, I get rejection email.

My question is what do you think has the most impact: my experience, communication skills, interest, behavior during the interview, excitement, etc.

I am really bad at expressing my emotions and when get nervous, I start talking too fast and start saying grammatically incorrect sentences. Also, I usually do not ask follow up questions to the responses.
