Promotion vs switch

switching is mathematically better for your compensation, but the exact decision rule is the promo-then-switch maneuver. internal hikes are anchored to your entry pay and choked by hr bands at 15-20%, while lateral moves bypass those caps entirely to recalibrate you at a 30-50% premium. secure the senior title internally to set a higher baseline, then immediately sell it externally so you stop paying the loyalty tax.

Depends but in most cases switch is better.
In some companies promo is good if they give good stock refreshers.
The stock and increment can add up to more than the jump you'll get while switching. But it's quite rare. You can calculate numbers for yourself
