Final interview is like chatting with recruiters about your previous working experience with people...the will ask you about different situations and how you would handle them (example: what did you do when client was mean to you..etc.)...it is actually pretty relaxed so don't worry about it...they do go into details, so they don't ask many questions but few and they want detailed answers...you will be nervous when you walk in but they will calm you down in a minute...that's how it was with me...and you don't even know how the time flies in there...45 minutes sound a lot of time but it is actually not, beacuse on starting you will go thru documents and photos and that takes also some time.
Good luck and just be you!
