I also think he could prepare himself for such interviews. But, one week? Well, that depends: - is it one week as in 7 days off, and spending at least 8h/day?

I also think he could prepare himself for such interviews. But, one week? Well, that depends: - is it one week as in 7 days off, and spending at least 8h/day? Then I would say, it may be enough. It just takes one problem you haven't seen before (you haven't prepared for) and you are out. - is it one week as in 5 days, and 2h/day (let's say, after dinner?). Then I don't think 1 week is enough. Around a month would be needed to match the previous scenario
