Is hopping to a BB and asking for 8k with 5 years of exp too much or too little? I come from a lower tier bank currently earning 6+.

See how well you do at the interviews lor

I've already passed the interviews and being asked on my expectations (even though i've asked them to first share their budget to no avail). just wondering whether quoting 8k is too high/low, don't want to price myself out of their range or discount myself too much either.

Aim for 20% increment anything else is a bonus

Would such an expectation be the same if a 20% increment still puts one slightly below the market avg? Seems like basing off previous salary can always be a double-edged sword depending on situation.

If you are below market the only way to save yourself is to hop frequently, with a stopover at at least one high-paying coy. Do well at interviews and aim for 30%+ increments.

Else if you are average to slightly above average for your YoE and function, I'd say 20% is a good benchmark to aim for.

5 years exp for Ops and asking for 8k? Tan ku ku la

Very possible. Esp in BB. Friends in ops grad program alr hit 8k at 4 year back (senior assoc).

Would this be the case for only the top tier bbs (gs/jpm/ms)? Or one can expect the same for other bbs like cs/citi/boa?

Depends on which BB. If GS/JPM/GS, 8k is well within their budget for 5 YOE. Other BB, most likely not.

(Currently at GS/JPM/MS Ops. Have taken part in recruiting for the company as well)
