This is right.

But as a rule of thumb, you need to be rated once at each level. So a high flyer can expect to promote every 2 years since ACN runs solely on meritocracy or based on how much managers fight for you at the annual round table.

Been quoted 6 to 7 for an Analyst to reach Snr Mgr but again, you have to be at the top of your cohort every time.

But the good thing is, ACN pays pretty well except annual increment is crap and bonus is capped at 2 months

Analyst - 4.1k
Consultant - 5.8k to 6.5k
Manager - 9k to 10k
