Gentle men dressing
Make an effort, good first impressions, body language, confidence
For 3 years I have been going to interviews advertised by servo and every time I'm unsuccessful. Even though t have experience and certificates. Makes me wonder than, what the he'll are they looking for.
Same as any interview clean, tidy, shirt/blouse, pants/dress, proper dress shoes
Formals if u are from outside. for internal vacancies you can put on unifroms.
