How do I apply for a job at Walmart, do I apply online or in person

Online

I am not sure. Nowadays I would apply online first, you have to be computer literate today, and see where the job openings are. Once you have determined the store or location you prefer, then go in person to talk the PROPER Manager. In 1970 I went to a particular Alpha Beta Grocery Store, as I liked the location close to home. I applied for a job in person 8 times in 7 days, to the Store Manager. They started me at 6 hours a week just to shut me up!😂 I worked my way up to 36 hours a week within a month. I worked 16 hours the first week, but was only scheduled for 6! I never worked only 6 hours as scheduled, always 16 to 36 hours weekly. When I was called to come in quickly for emergency coverage, I was there within a half hour ready to work. Started out as a "Box Boy" @ $1.35/hour.

I would give them a call & ask them how to apply.

Online is always the best way to apply for a job especially if they have a website
