I am a senior manager at Oracle - so I know how offers at Oracle work. If we see 7 years of experience, we target IC4. The offer OP mentioned is a solid IC4 offer. So, at the very least he did excellent in his interviews. Then, why on earth would we give him IC3. Having personally hired 8 people over the past 3 years and extended offers to about 15 or so, I know that OP is lying about some part of the offer.
