It's happened to me a few times with some non-US/MC/SC firms this cycle (e.g. Addleshaws and
Dentons) where I worked really hard on the application and didn't even get to a VI stage. I really was interested in these firms too. On the other hand, with US/MC/SC firms this cycle, I've not received a single post-app PFO (i.e. I always made it to the next selective stage, whether that's a VI or telephone interview, or AC). I am starting to think firms are making judgements based on whether they think I'd accept a TC with them sometimes? Like how do I convince them?? I promise I would????
Edit: Just to note, Addleshaws had a non-selective test so it's entirely possible that I failed that
