I'm quite happy to try to demonstrate how I think, but I hate hate hate leet code because A) it's not relevant to showing how one thinks and B) I've read so much dunking on it on HN that I'm now stopping interviews when they pull out the hackerrank or live code to say 'without using the library, reverse this linked list'.
That sounds awesome! Wish I got the chance to do more hands-on interviews in the mobile dev space, most of my interviews just end up being run of the mill leetcoding.
