How was your first day of working in IT? Doesn't matter even if it is too old

I remember my first day at WITCH. Orientation. HR told us to never call anyone as "sir". That struck me deeply, and I do use the term but only with 50 years+ CXOs, no one else.

First day orientation.. Hr played a video on how we supposed to reach out coffee machine in line/queue. It looked like prisoners. My Prisoner life started since then.🤣🤣

My first 2 days were orientation in Taj Banjara, Hyderabad. First time went to 5 star hotel, that too for joining my first job
