It’s ok to speak proactively about the points you want to make in an interview, you don’t have to wait to be asked.
Prepare your strongest stories in advance, and if you don’t have a chance to share them feel free to say:
“One other experience I wanted to share that I believe will help my candidacy….”
“Can I tell you about some work I did that was similar to the tasks I would do in this role?”
The answer will always be yes.
