In large organizations it can take a little time for you to receive a response. This is not because they are not interested in you, but rather because as a large organization, the volume of applicants that they receive is significant and typically the people who are responsible for making hiring decision and getting the communication back to the candidates are pulled in a number of different directions. This causes other priorities to move to the forefront, but give them a few weeks and they will get back to you. I suggest that if you have not heard back from them after 2-3 weeks, send a follow-up e-mail to the company asking for an update on your status. This should prompt them to provide you with an update.
