While much of the Mishna was after the Churban, parts are before. As I
mentioned The Gemara in Shabbos (15) states

"The Nesi'im during the last 100 years before the Churban were Hillel,
Shimon, Gamliel [ha'Zaken], and Shimon (the father of R. Gamliel who was
Nasi in Yavneh)"

These people all figure in the Mishna. Hillel and Shammai were certainly
well before the churban and therefore so were at least some of their
students, Beis Hille and Beis Shammai.
