I am in the process of getting an offer from Google and am looking for tips on elements I should ask for/negotiate as sign-up bonus, stocks, relocation package, other benefits. Is a sign-up bonus common? Does Google cover expenses I would have because of the relocation like break of a house/car lease?
Sign-on yes, stocks definitely yes, relocation and other benefits definitely no. You get fix number of points based on the level you are hired for relocation, house/car lease is covered but you have to pick and choose within those points.
Sign-on is common but without competing offers don’t expect much.
