If you don't have "managed=true" in the "[ifupdown]" section of
"/etc/NetworkManager/NetworkManager.conf"?

If you don't, NM will ignore the NIC that you've defined and set up in
"/etc/network/interfaces".

How are you setting the DNS servers in "/etc/network/interfaces"?

The only way that you can do so (using "dns-nameservers ...") is if
you have resolvconf running and "/etc/resolv.conf" is a symlink to
"/run/resolvconf/resolv.conf".

(If you don't use "dns-nameservers ...", you have to use
"/etc/resolvconf/resolv.conf.d/{head,base,tail}" to set the
nameservers in "/etc/resolv.conf", unless you want to use those that
you get via dhcp.)
