Some companies, like Microsoft and Oracle, do offer salaries comparable to that of FAANG companies at junior levels; however, at senior levels, the difference becomes more prominent. To earn FAANG-level salaries at a Tier-2 company, you would need to work longer and get promoted to higher levels or have specialized skills that a particular company needs.
However, at the same level, with the same experience, it would not be the norm to earn as much at a non-FAANG company as at a FAANG company.
