Insight day advice

I’ve just graduated from a top 5 CS uni (results pending but should be a first🤞).

I’ve been applying for grad jobs but haven’t gotten anything. I’m looking at entry level and immediate start roles so will take that and reapply for smth bigger for next year. I’ve got this Amazon insight day next week and I wanted to know if there’s anything to be aware of? Has anyone actually secured a role by attending one of these? I will network as much as I can but I want to make the most out of the day so I’d be really grateful for any advice!

Cheers

EDIT : I do have prior experience, having completed an internship each summer prior.
