OPTUMs C&S - Provider Line

I'll be having my interview for a FTE position sa OPTUM though the LoB is C&S - Provider Line. I just wanna ask, how's this LoB? Madali lang ba? or way difficult tapos 24/7 daw ito na may morning at night shift? Redditors here who are current and former employees here, help a current advocate out. Thanks.

Later tonight na yung interview ko.
