Lilly Limerick as a place to work

I've seen a couple of roles advertised in the past 6 months in Lilly Limerick that look interesting. Can anyone here tell me about Lilly Limerick as a place to work.I understand that the hybrid requirement is to work 4 days on site, what are the hours of work for office based employees/ is there flexibility in relation to hours of work? How would you describe the culture there etc..
