Whether it is through Skype, Microsoft Teams or Zoom, everyone is getting used to shifting to online methods of communication. This means that even employers aren’t sure what rules to set.
As a rule of thumb, almost all employers will keep the rules the same as they had them before. So, do your research and find out if they would ask for a smart dress code in a face-to-face interview.
If it isn’t clear, try looking at what kind of attire their staff wear in staff photos on the website. By fitting in with their usual dress code, you will seem like a good fit for their company culture and shows that you are proactive at doing your research.
