My TPM just asked me to upload the files I changed on the server, I asked if they don't use git (today is my third day in this company), he said no. And today is also my last day, because I resign at the end of the day.

I should learn from you. Here I am migrating everything to git and teaching the absolute basics of development to the dev team who show no interest because FTP and shared directories work better. No worries, got a meeting monday for a position somewhere else.
