May 7 at 13:54 comment added Alexandre Eremenko In the smallest case $n=2$ this is equivalent to $f_1/f_2$ to be rational, and for a power series there is a rationality criterion in terms of Hankel determinants (all sufficiently large ones vanish). Is this a satisfactory answer to your question for this special case?
