Great question. I would just approach it the same way! That has worked before for sure. For example, you could ask a small question e.g. what’s the number one thing you look for in a graduate xyz? Then progress back and forth. Naturally, you’ll be able to then ask about what you should focus on to land the position etc…. and may go to a chat anyway! But given the application is closing in 2 weeks, it’s probably worth getting your application etc. ready to send very soon and submitting asap anyway with an alongside message too. It’s a bit tight to wait too long!
