The traditional word CV often ends with: References Available Upon Request. Sometimes, you’d actually put down the names and contact details of 2 referees so that employers can reach out to them directly.
Now, if you wish, you can get one of your referees to record a 30-60 second video where they commit the reference to video. This is a superb way to go as it means they don’t need to do it repeatedly for many employers or perhaps that employers can watch it and then contact them just to ask follow up question.
This is digital so you can also add the referees WhatsApp, Google Meet number link or Skype handle, etc. Future employers can schedule a call using Calendly and the whole process becomes extremely smooth for the employer. This wins you big points when being considered against other candidates.
