<p>LoL I would say that depends on the lab. Some are large, some are small and intimate. Some primary investigators think new people should do grunt work (like cleaning flasks) but others find it more important to teach the young basic, important skills. Set up meetings or correspond by email with labs that interest you so you can find out what kind of lab you’re looking at. Just be honest and ask “what will I be expected to do? what will I get out of working in this lab? what opportunities will I have?”</p>
