Corporations as a group offer a variety of jobs．Most large companies send people to colleges to interview graduating students with the required academic training．A large university may have more than 500 companies a year knocking on its door．Big firms are your best place for a job because their normal growth, employee retirements, and turnover (补缺工人数) create thousands of jobs nationwide each year．They are quite attractive for job seekers.
Corporations, however, illustrate the rule that the biggest isn't always the best．Many small firms with just a few hundred employees have positions that may correspond with your profession goals, too．Such firms may not have the time, money, or need to send people around to your college; you'll probably have to contact them yourself either directly or through an employment agency．Don't ignore these little companies．They are perhaps beneficial for you．Their salaries are usually competitive and the chances for advancement and recognition even stronger than those of a big firm．You could become a big fish in a small pond, reaching a high-level position more quickly than you would if you had climbed the more competitive ladder of a corporate giant．What's more, a small Firm can develop into a big corporation．Many famous companies such as Microsoft, Amazon bookstore, Haier, are just from small ones.
For example, a small company may need a bright engineering, accounting or management graduate who would report directly to the senior vice-president of engineering, the company controller, or the general manager．In large firms it may take years to reach that level and accumulate similar in-depth experience．In addition, responsibilities may come faster in a small firm with less specialization and fewer lower-level employees to receive delegated authority.
It is critical that what is your want indeed from the work．No matter what kind of company it is, big or small, if it meets your needs, it is a good one.
