Not really. Frame or not frame a house would be a core requirement if the jobs needs that. Having used DI is not a core requirement. It is something you can learn in 2 hours if you are experienced. It might be like a carpenter not having used a specific tool but instead used another tool and there is a 4hr training at the local college on how to use the new tool.
Or like a pilot doesn't get a job because they flew a slightly older Airbus model and need to do some sim time.
