Curious about career as a device sales rep.

Hello all! I am a current sophomore enrolled at the University of Arkansas. I have a few questions about the field, and am interested in becoming a rep. I am currently a business exploring major because I realized I wouldn’t want to be a nurse after working as an EMT for about a year, so I switched majors and I have a few questions.

What majors do the biggest companies look for when hiring on new candidates?

What are some companies that would help feed me into bigger companies/what does the pipeline look like to get into the field?

What is the work like balance at bigger companies?

How consistent does the pay stay?

What are some things I can do now to secure a career in this field?

I am open to long work hours and don’t mind a weird work life balance (am kinda used to it as an EMT and full time student), gore doesn’t bother me and I don’t get stressed easily. If anyone wants to connect on LinkedIn or have a conversation, please reach out, as I am open to as much information I can get! I appreciate anyone who had the time to respond, thank you and have a great day!
