What is the ruling on the banking transactions of the company where an accountant works, and what is the ruling on his work in the company and the money earned from it, and does this ruling apply to all employees?

If a company deals in prohibited interest (riba), then it is not permissible to work in its execution, writing, or recording, based on the hadith of Jabir: "The Messenger of Allah, peace and blessings be upon him, cursed the one who consumes riba, the one who feeds it, its scribe, and its two witnesses. And he said: 'They are all equal [in sin].'" However, if your work in accounting does not involve direct engagement in usurious acts or assisting in them, then there is no harm in you continuing. The same applies to managers, engineers, and others. Shaykh Ibn Uthaymeen was asked about an employee working for a company that deals with riba, and he replied that as long as the employee does not write riba contracts, nor witness them, nor take them, nor give them, then there is no harm upon him. There is no harm in taking end-of-service gratuity, travel tickets, and salary as long as your work is free from what is unlawful and from assisting in it. It is advisable to counsel the employer to fear Allah and to stay away from riba, and to deal with Islamic banks, and to seek lawful financing methods, for the consequence of the unlawful is evil, and it prevents the acceptance of supplications and deeds, as the Prophet, peace and blessings be upon him, said: "Indeed, Allah is good and accepts only what is good..." the hadith. And he, peace and blessings be upon him, said: "Every body that is nourished by unlawful earnings, the Fire is more befitting for it." And provision is predetermined, so one should not rush to obtain it through unlawful means.
