How to dress for a job interview in summer
Ask the hiring manager about the dress code.
You will want to dress appropriately for the work culture of the company or organization with which you are interviewing. Call or email the hiring manager to confirm your interview and ask about the dress code.
Check with the norms in your industry, and if you are unsure, opt for something more conservative and neutral. Clean, mend and iron your clothes before your interview.
