Here's what people have said about working and interviewing at Costco Wholesale.
AM schedule on Wednesday and Saturday ,
Nights on weekdays
They certainly have a wide range of shifts that can work with yours, but sometimes, those are positions you have to wait for an opening in. So say working in the Bakery from 3pm to 9pm works perfectly for you, you will likely have to work in a different department at a different shift until that position becomes available. So I will say yes and no, it depends on how much flexibility you are looking for. They are decently capable of catering to employees who show a good work ethic and have a positive attitude, but not working on the weekend is not something they are usually to thrilled about.
