Any connections you can make with previous employees will also be beneficial. Bear in mind, though, that ex-employees may have departed with a chip on their shoulder. Along with general company information, it's also helpful to learn as much as possible about your particular department or work team. This includes your immediate supervisor, co-workers, and others whose jobs will impact your standing in the company. Establish a reputation for being a good worker.
Most companies view the first three to six months as a honeymoon period for new employees.
That's the time to get adjusted to the organization and to prove one's worth as a valuable worker. Companies don't expect perfection from new employees. However, they do expect them to do their jobs as responsibly as possible, learn from their mistakes, and make an increased contribution to the organization. To establish a favorable reputation, show yourself to be reliable, dependable and hard working. This doesn't mean being an apple polisher, but it does mean focusing on the tasks that you were hired to perform.
