Set camera/phone to landscape mode and either take a selfie video or have someone take it. The background can be a light colored wall or an interesting landscape including your office, lab or outside of your building or other interesting space or activity that highlights your position and/or what the company does.
EXAMPLE: Hi, my name is Joe Smith and I am studying 'economics' at 'name' university/college. This past summer I worked in the marketing division at 'company' where I analyzed social media and the impact of the company's efforts from the start of 2018. It was an interesting project where I learned how businesses leverage social media to raise their brand profile, promote their products and services and engage their customers. I was really impressed with how smart and nice the people are at 'company' and look forward to keeping in touch and hopefully working there when I graduate.
