What are the chances of getting interviews with my stats?

Hi All,

Long-time lurker first-time poster.

I have a really unconventional background and wanted to see what people thought my chances were of getting interviews for consulting firms such as ATK, LEK and OW.

My background:

I am in Melbourne, Australia.

Average student in High School and studied Media Production at semi-reputable university. Just cruised through university as an undergrad and didn't really like my course. I think my GPA is like 3.0 equiv.

Went overseas for a year, came back and decided to study finance as a postgraduate. Been working my ass off in finance (I think equiv. 3.8 GPA), very strong ECs (ran student investment club, on faculty board, charity volunteer), and over the last Nov-Jan period I did an internship in a sales role at a small bank. Most recently I have been doing a client/admin role at a retail stock brokerage in a large local bank (think Bank of America).

I networked like crazy this past year and got interviews at 4 bulge bracket investment banks. I received an offer for an internship and I will be be working in the IBD for about 10 weeks starting in November this year.

I have access to networks (mentor who is in banking has friends at Bain etc) and have plenty of friends that are very good at case studies that I can prep with. I am not the most quantitative person but I work my ass off and I am extremely confident in interviews.

Also, my school is a "target"

Thoughts?

Edit: my primary concern is my low high-school marks and undergraduate GPA.
