for S&T: Application --> Interview --> Internship --> Job

Assuming that you're applying through your school's targeted recruiting and not the online black-hole, your stats seem strong enough where you should at least be landing an interview with any firm to which you apply. I'd suggest looking over or having a knowledgeable third party look over your application materials, as there may be an ignorant taboo somewhere within your documents that is getting you dinged w/o interviews.

ivy target? how many seats in the interview room?

Update: Of 5 applications, I have 3 outright rejections, and 2 interviews.

Am I doing something egregiously wrong, or is hiring that tough this year?

hiring is tough this year i guess. with ur resume and school and work experience you should be getting interviews with every bank at least

any ideas about the last part of the question?

"Also, if given the internship offer, what are one's chances of getting a FT offer? Does this vary from bank to bank?"

This year, I am almost positive that rates from SA to FT will go down given current market conditions.

Like grinder86 said, full time offer rates will probably go down considering several banks are about to lay of a lot of employees/continue with the writedowns. However, in the past, full time offers are theoretically contingent upon each individual's performance. A manager at a BB once told me that their program works such that if every SA performed up to their standards, they would have the capacity to extend FT offers to ever SA. This will vary from bank to bank. Most HR people will say that their hiring will not be affected by the current market conditions. This may or may not be true. I guess we'll find out in a few months.

Why not just take less interns instead of having that FT rate go down?

in which range was that rate roughly during the last years? have really no idea about it...
