You have posed an interesting question.
An interview provides equal opportunities for both parties.
One wants a good candidate.
The other's expectation is to get the job.
Even in the best of conditions, any interview panel will be reluctant to consider a job hopper.
However if they are desperate to get a candidate and they can't find anyone else, he may get a chance.
As far as the candidate goes it is purely a mathematical chance for him.
According to me during the interview he can be frank and brief about what he wants to say.
