These seem pretty standard for 2 years experience?
That's more than the standard new grad Rsu grant at Google/FB/Microsoft/Amazon, which vests over 4 years. I can't imagine that 2 years of experience plus some negotiating quadruples the stock signing bonus.
Everything else seems high, but within the realm of possibility...however, the RSU grants seem to be abnormally high to me. OP claims that he gets the listed amount per year in stock, not vesting over four years.
