Breaking into T2 strategy consulting firms from non-target school

Hello,

I go to Boston University, majoring in finance and accounting. My GPA is a 3.85 (Top 3% of my class) and am a rising senior. I worked at Pioneer Investments my Freshman summer, Reserve Bank of India my Sophomore summer, and PwC (Assurance) my junior year summer. I recently got in touch with a friend's dad (A principal in charge of a national service line) and he/she got me into the interview process for Deloitte S&O. The recruiters got back to me and said I would be a very competitive applicant. I have studied extremely hard for these interviews. Already have 40 live cases under my belt and have just started preparing for the behavioral portion. My interviews are in September. Finally, I also have an offer for Assurance as a back up from PwC.

1) Given all the preparation I have done, I would like to also apply to other firms in the event I do not land Deloitte S&O. I would love some guidance from you monkeys on which firms (ie ATK/LEK/Accenture) to apply to given my circumstances and how to go about applying - I find it very difficult given their sites to find the correct place to apply.

2) Furthermore, I would love to apply to PwC's Strategy& given I already worked there over the Summer. When I asked my recruiter she said she wasn't sure if they'd be able to consider me. Should I tell her I am being considered for Deloitte S&O in order to show I am a competitive applicant or is this a bad idea for a couple potential reasons?

Thanks so much in advance
