Questions about Analyst to Associate promotions

Hey everyone, I will be joining a "low-tier BB" (WF/DB/RBC/UBS) in NYC as a first year investment banking analyst in the M&A group this summer. So I'm from a non-target (top 20 US News liberal arts) school and I can count the number of alumni in PE on one hand. Our alumni who work in PE are all at lower MM funds (300-500MM funds) even though they did their analyst years at a top tier BB or EB. Rest of my alumni network in finance are career bankers. That being said, I know my chances of exiting into PE are slim to none and I will most likely have to choose the career banker route or exit into corporate after 5-7 years on banking.

My bank has a 2.5/3 year analyst program, and I had a bunch of questions about AtoA promotions that I'm hoping some of you guys may be able to answer. Thanks!

1) What is the base pay for 1st year associates? I've heard both 125k and 150k, but any predictions on what it'll be in 2021? What about 2nd and 3rd+ year associates?

2) I know MBA -> 1st year associates get a huge signing bonus. Does that also apply to Analyst to Associate promotes? If so, how much?

3) I've heard that you get like a 2-3 week "sabattical"/PTO if you are an A to A promotion... is this true?

4) 3rd year analysts at my bank told me their hours are significantly better as 3rd years than 1st years (65ish hours on average 3rd yr vs 80-90 1st yr). How are the hours for 1st year Associates who are A to A promotes that already know how banking works?

5) What do bonuses look like for A to A promotes? Is it higher than MBA counterparts since you've been doing this for 3 years now?

6) More specific/personal info on associate comp (base + bonus) in the M&A specific groups for Top Bucket would be super helpful. Thanks!
