Time to give up on pupillage?

In my first year of making pupillage applications, I got several interviews. However, this time round I had no luck whatsoever. What’s gone wrong?

Having recently completed my BPTC, this has been my second year of applying for pupillage. My grades, university and work experience are good, although I don’t have a First.

I know it takes many people several years to get pupillage, but is the fact that I’m actually becoming less successful at getting to interview a sign that I should call it quits?
