<prompt> Human: So I know best thing to do would be to talk to my HR. but my companies HR dept is very weak. small, not very knowledgeable, slow to get things done, etc all because its a small dept in my company basically, if i ask my HR dept, they will do their research first and get back to me.I figured i would rather ask here for the generality of it.Basically, after 60 days, I can start contributing to the companies 401k. As well as somethign called profit sharing. it is through vanguard.However, tehre are no information on HOW to do it. as well as how the contribution works. the only info i have is that its a 100 match on first 3 and 50 until 5. I dont even know what the 3 or 5 mean. is it per paycheck? per annual income? etc and how do i know what percent i am at? since i will want to max out IRA after i get my matchingalso, I dont even know what its vesting period is... I heard a rumor from one guy that its like 7 years or something. which, sounds srsly ridiculous...So how do i get this info? if i simply go to my vanguard account and go under my employer 401k plan, will it be all there?  <response>: You need to talk to HR. Every company does it differently. Sometimes there is a form online you fill out, sometimes its paper.
