KGS interviews were similar in approach (minus the question about which other schools DD had applied to and minus the "bring and object"). But warm and meeting the teacher beforehand and having a better feeling for the place.
I agree that Emanuel has handled the admissions very well and, for quite a few people, that will push them up their preference list (it has done with us). Similarly KGS, who has been really good at keeping in touch and making DCs wanted. Of the schools that we have applied to, these are the top 2 in so far as the running of the process goes.
