Is it too late to start networking in April?

I go to a semi target school with a decent GPA and extracurricular activities on my resume.
I am an econ major and I thought I wanted to go to grad school (e.g. law or PhD) but I got involved in various finance projects and started to have thought recently that I want to pursue IB. I did have a finance internship freshman summer like randomly through connections so I have that under my belt as well.
I know Citi is done basically and so is DB, but there are also plenty of BB firms with deadlines in last August or early September. If I reach out to the Analysts right now are they gonna think I'm an idiot for waiting till April to start networking? I am just a bit worried because I know a lot of IB crazed people were networking well into last winter break or something.
If I can have a shot I am gonna start sending those damn emails asap.
