This is the first and foremost thing to do during campus placement drive. You should never miss Company’s pre-placement talks and presentations. The reason you attend these sessions because most of the times questions in HR interview are asked directly from what was conveyed during company’s pre-placement talk during campus placement drive. It gives you a background of what company is doing, domain in which company is working and most important, technology that company is working on. This helps you in identifying if this is the right company for you.
