Can be rewarding, but a lot of work.
Pros
Can gain great experience in retail and B2B style sales in person and in cold calling. Pretty good quarterly bonus structure if you're able to have success in sales with opportunity to nearly double your salary in year end bonuses. Will learn a lot about, not only paint products, but general construction. You get what you put in, and can be rewarding financially and career wise. Opportunity to grow if in a larger market. Still hourly pay as assistant manager, so can get overtime (though city management might get mad). Will learn how to run a business with P&L overviews and maintenance of warehouse stock.
Cons
Management can be hit or miss on. Sales Reps are hit or miss, as well, on if they bring a job to your store or another location because their relationship to the manager. City/ District management push unrealistic expectations and change month to month on what they want pushed (i.e. New accounts vs. pure sales) 401k match is rug pulled to give ceo a bonus. Staffing is cut forcing salaried managers to work over 48 expected hours causing burn out. Assistant manager is expected to handle all paper work, as well as 50+ calls a week, and 50+ cycle counts per week.
