Scheduling between the two

Working hours overlap from 9:00 am to 4:00 pm TRT, which is 11:30 am to 6:30 pm IST. Anything inside that window falls in the normal working day at both ends.

A note on IST: it can also mean Israel Standard Time (UTC+2) and Irish Standard Time (UTC+1). This page means India Standard Time, which is what almost all searches for IST want.

Turkey Time (TRT) is used in all of Türkiye, on a permanent UTC+3 since 2016

India Standard Time (IST) is used in all of India and Sri Lanka, on a single UTC+5:30 offset with no daylight saving
