You should interview any redeployees who you think might be a potential match and also think about using additional selection methods. You should follow the interview panel framework to decide who is on the panel and the interview guidance will help you plan the interview and decide what questions to ask.
These will then help you to properly assess the redeployees ability and whether they are at least a 70% match to the job.
You will need to let Redeployment know the outcome of the interview(s).
If there isnt a match you will need to give feedback to the redeployee using a matching form.
