Just finished my board interview today. Feel free to ask any questions, but it basically went down as others have said other than I actually had 4 officers on my board instead of 3. I had to knock 3 times, enter and report to the board, then sit when told.
They asked questions like:
What's do you think the differences between a commissioned officer and warrant officer are?
Does your family support you in your decision?
What kind of responsibilities to you think you will have in the Army as a leader?
What are the Army values and which one is the most important one to you?
What personal value outside of the Army values do you think is important?
And a few other general questions regarding leadership and how I feel about the Army.
I was really nervous for the first few minutes, but warmed up to everything after a few minutes and did well. They really just want to see if you are a good fit.
