I think this makes for an EXCELLENT interview question. Engineers with strong opinions are better than engineers who just do whatever others want and haven't thought deeply about anything. But even better is an engineer whose opinion changes as more information becomes available. You want to hire the person that is capable of both making a thorough case for one approach, and is mature enough to admit that that approach is suboptimal and then go implement the optimal one.
