Do you need to wear formal clothes for job hunting in the workplace?

Whether it is necessary to wear formal clothes for job interviews depends on specific issues:

If the applicant is applying for a position directly facing customers, such as: bank teller, bank lobby manager, vehicle attendant, etc. It is necessary to wear formal clothes to the interview because formal clothes will also become their work clothes in the future.

If the applicant applies for a position that does not directly face customers, such as a technical position, a financial position, a design position, etc. As long as the dress is clean and tidy, it can be worn in line with the general occupation. If you dress too formally, you will be more abrupt than others.
