Apr 2023

I managed the store alone 8 hours a day, and had a lot more responsibility and was confident in my ability to keep the store clean., run all the reports every night, and count all money made each day and then close and lock up the store


My boss yelled at me often.


that I got to be alone during my shifts

Jun 2021

Lots of refinery locations for networking


company culture, lacks diversity, rigid work structure, no flexible work schedules, no remote work, limited collaboration, corporate office is in rural Ohio


High Compensation, Pension and 401k

Mar 2021

Great exposure to talented people and a variety of work.


The large size of the company means that administrative tasks including promotions come slowly.


The work-life balance is significantly better than working in public accounting.
