If you ever work at a company with a 401k, make sure you read the matching rules and vesting rules for company contributed funds! If you are not earning 100% of company matched money, you're throwing away money that the company already allocated as part of your total compensation. Maybe that's OK if you want to take the cash home instead, but at least be aware of your options. Also make sure you look at fund fees; some employers will let you continue operating your 401k after you terminate employment, but you may pay higher fees. Some funds may look great but may have very high fees. If your company makes automatic contributions (not matching; straight-up contributions) make sure the cash is actually invested in something. Company contributions may have wildly differing vesting schedules, too, be aware.
