He has not had any lessons.I'd have thought any decent employer would give him a bit of leeway, as long as he was well into lessons with a test booked in six months. Or maybe he could do one of those intensive courses where you learn to drive and take your test at the end of a week when they're running again, not cheap but worth it for a good job.
I would gladly pay for a weeks intensive course but nothing is possible with this lockdown.
