What is the ruling on working at HSBC Bank as a personal data entry clerk (updating data, addresses, and contact methods) without dealing with money or customers?

It is not permissible to work in interest-based banks due to the prohibition of aiding these banks which wage war against Allah and His Messenger. The warning against usury is not limited to those who consume it and those who provide it, but extends to anyone who contributes to it, even with a line on a paper. It is obligatory to denounce these banks, and the least form of denunciation is to abandon them.
