I had a friend with a few offers from top places (of the google, facebook, microsoft sort of variety) who ended up taking one for about 100k a year base plus about 500k stock vesting over five years. That was definitely atypical, though, particularly on the stock front.
When I graduated from college in 2011, my good friend and classmate went to work as an engineer for a high-frequency trading firm. They offered him a $160K base salary and a signing bonus of ~$20k.
