A&M does not get you a job. The Aggie network does not get you a job. Your education and Aggie Network can help you get a job but securing a job is up to you as a potential employee. The Aggie network can create contacts for you but you are guaranteed anything once you graduate. A&M affords you an education from a highly respected university.
Take advantage of Your years at A&M and make contacts, attend the job fairs etc and make the most if who you can be.
Aggies do like to help their own (other Aggies) if and when they can but there is no guarantee that you will be hired for a job just because the owner/boss/recruiter is also an Aggie.
You can interview with whatever size and type of company you want when you graduate. You are in charge of your own destiny.
