When it comes to business, appearance and demeanor play an important role. however, you have to adjust your appearance to the job you want and the same goes for when you are doing business with clients or with investors. this aims to show how important appearance is to become a successful businessman. because when running a business you have to serve clients, build networks, strengthen relationships, and be a leader, appearance and demeanor are aspects that are as important as business skills.
Even though not everyone has business instincts like successful business leaders, we are all capable of showing our best. but not only appearance, skills and abilities are part of the factors that are equally important.
In work, the requirement to look attractive is not to see how beautiful or handsome the candidate is. but to see the seriousness of job applicants. if the job applicant tries to look attractive, dress neatly and so on during the interview. then it proves that the job applicant has tried to give a good impression of appearance.
it's different if when you dress according to your wishes with a disheveled appearance, surely the employer will think you are not intending to and are not serious. related to the points you convey, it all depends on each individual.
and for point 6, at least he must try to look neat and have a good attitude. then he can show his skills and qualities during the interview session.
Appearance, attitude, and style of speaking in good mastery are perfect aspects when we are going to face a potential boss. At least that reflects the seriousness as you say. A neat appearance shows that the person is serious in terms of cleanliness, tidiness, and prioritizing rules. Attitude means that he knows who he is dealing with and this behavior is the most important thing, politeness shows authority. Speech style means that he knows what is being discussed according to his capacity and in accordance with the field that the client wants. Coupled with qualified knowledge, it gives plus points that he will easily communicate with anyone.
