msft 63 offer vs amzon 65 vs google L3 求比较

Currently I got three offers from MSFT level 63, Amazon L5, google L3( interviewed for L4, but downleveled  to L3, first try appeal reject, but recruiter still trying to fight for L4).  
Here are the  TCs:
MSFT 63 standard offer:
Base: 190k, rsu:200k, Joining bonus: 50k. Haven't negotiate yet, can negotiate a bit more. Frist year TC:270k without cash bonus.
Amazon L5 : first year TC around 300k.
Google L3: haven't discussed the offer details yet. Still fighting for L4. I bet with L3 it would go above any of offers in MSFT or Amazon.
Location: Bay area
YOE: 3 yrs (started with Phd in engineering, not CS)
Any comments would be much appreciated. Thanks so much for your inputs

软63 匹配 狗L3？
Meta 凉了后，google 真的是 肆无忌惮地low ball 啊。
选软吧，google 再这么下去，就是下一个微软，你进去就相当于 59。

亚麻应该可以谈到更高，狗也太过分了，phd加三年经验给L3

微软63比amazon L5高半级吧

狗L3没办法beyond另外两家吧，L4可能都无法beyond amazon吧。

Amazon L5这个包有点低

狗的l3 package应该是没法和另外两个比的。

amazon L5可以更高
软确实就这水平
🐶家L3的话应该是所有包里最小的。。。

狗L4都不一定能300k 更何况L3 看钱的话软和麻吧

先说清楚亚麻的offer按照什么股价给的

微软63是Senior
