Ok, I currently work for a grocery store, and for the summer I would like to get more experience in the computer field. There is a company that I am interested called Micro Trend Computers. They do things like build custom machines, service, upgrades, and networking for businesses. I KNOW that I am qualified for the job after going through the Cisco Networking Academy courses, had a month long internship at a local hospital working with their MIS department, and have worked with computers everyday for the past 4 years, building, upgrading, and repairing. My question is this, should I just walk in the store and ask the person at the counter for an application? Should I find out if they are hiring first?
