MBB/T2 Lateral Recruiting Pre-MBA in the US

What is the pre-MBA lateral recruiting process (1 to 3 years work exp) in the US? (at MBB/T2 firms) I see these roles pop up periodically and couldn't find much "how to" advice about switching from a lower ranked consulting firm to MBB/T2 without an MBA.

Specifically: 1. Is there a typical timeline (length of process, time of year) for lateral recruiting? spring? 2. What specific backgrounds did these pre-MBA lateral roles look for, if any? (just Ibankers? 3. Are there different steps in the funnel/process (e.g assessments, rounds, phone screens) ? 4. I assume that applying blindly is not a good idea, so what type of referral/buy-in should you have at the target firm? 5. Do former consultants typically take a title downgrade? 6. Are expectations any different than campus recruiting? What different questions/performance levels are expected.
