Perhaps, your so-called friend doesn't meet the qualification of FINANCE team...It's either she/he is not capable of doing her/his work and/or he/she is definitely not qualified to do the job even if he/she has a credential. Maybe, she/he is not smart enough to do the job in FINANCE. I know a temporary girl from QR who has acquired a good position in Technical because of her experiences that she has obtained while working in FINANCE.
