As I wrote earlier I have no clue =) However, I feel like it is way easier to get a job in e.g. London or SF since it is unsubstainable to live there for most people so there is a big churn. In smaller UK villages you can probably live a good life working at Subway doing sandwiches. Not so much in London. So you wont get the small village Subway job becouse the current holder does not quit. E.g. when I lived in Palo Alto I noticed a big lack of children so I assume you need to be rich to afford living there with them. So newcommers get the newly made parents jobs and so on.
