Australia student looking to apply for undergraduate entry level roles in the US

Hi all,

I am currently an Australian student who will be on exchange to UT Austin for the Fall Semester this year (August - December 2018) and I will be graduating at the end of November 2019.

I understand that the recruitment period for undergraduate entry level consultants for MBB and other firms being around September. I would love to take advantage of my time here and would like to participate in this recruiting season however because I am an Australian citizen and I graduate at the end of 2019 so I am uncertain as to whether these firms would even consider my application. I am very flexible and would love to work in any American office however I am aiming to apply for the MBB.

Can someone please advise me as to:

1. What the recruiting process is like for the MBB in the US? (e.g. how many stages/interviews/tests)
2. Prospects of success for a student from another country (i.e. Australia) versus a domestic student from the US?
3. If a student is successful, whether they allow the candidate to defer their offer a year to start of 2020 for the September 2018 recruiting season?

Thank you very much for any responses!
