High five to you for realizing you need to get in there and find some options to gain experience while you are an undergrad. Feel free to check out our programs at www.att.jobs/college.
We are looking for a little more time under your belt for some of our internships/development programs, but it is never to early to start investigating what's out there and gathering the skills, courses and contacts needed to turn yourself into the candidate of a company's dreams.
So many of the big tech companies have programs that could be an awesome opportunity for you, so take the time to do your research. Career sites are a great place to start. Networking is also a key component of not just finding the right internship, but of hitting the other area you mentioned...finding a good mentor. It can be an excellent boost to find someone who can guide your trajectory!
Best of luck to you in the future!
