I think it's great that you have to complete this assignment because it can be incredibly valuable to learn from a professional who is in a career that is of interest to you. It's often the next best thing to trying out something for yourself.
You may have some luck here if someone is able to answer your question with the details of their experience as a computer scientist. However, because of the nature of the assignment requiring you to have personal contact, I would perhaps suggest that you also use a different route to find someone to talk to if you aren't already. It is my understanding that it is against careervillage.org's policy for individuals to share personal information like email addresses. Other ways to contact someone in your field of interest would be to put a call out on your social media (i.e., asking your friends/family if they know someone) or using a resource like LinkedIn. With LinkedIn, you can directly message individuals who are in your area and who maybe work as a computer scientist at a company that you are really interested in.
Good luck with your networking!
