does anyone have any idea if you can read anything into open day application outcomes and your vacation schemes, ie. can you view an open day acceptance as a positive indication if you're already a few stages into an application process (and the opposite of course)?
Having been rejected by every single firm I've attended an Open Day at (in one cycle or another), they definitely don't indicate much in the way of positivity for that firm.
That being said, Open Days are a positive sign that your application technique is good- why would a firm invest in you as an Open Day candidate if they didn't see potential? Open Days are more competitive than many assume, so it's definitely encouraging.
I'm sure this doesn't need to be said, but they also demonstrate a real, authentic interest in the firm as well as a fascination with commercial law more generally.
