Yeah but it doesn't matter for TC's specific situation. As a new grad, the only negotiating factor you have is if you have multiple offers. Naturally, having multiple offers and herding them to the other company to bump pay will let you know your worth to not get lowballed. If you only have 1 offer and you get lowballed, its not like you can do anything about it, just work for 1 year, ask co workers how much they get and try not to get lowballed next year with your new set of offers.

Also, it looks like TC is using bigtech too loosely in this case. E.g. 70k tc for Visa is not lowball. while 70k tc for Google is lowball. Hard to give advise tbh. Feelings of year 1 low TC isn't the end of the world. Since he is in bigtech now, its easy to get interviews in bigtech that pay a lot better E.g Facebook. Just need to grind tech interviews. Ability in tech interviews != work capability.
