Worked as an Agent for years, lived the culture, felt it was horribly misrepresented by management. Geek Squad Culture is no longer a thing at Best Buy - which is a very, very bad thing. Having literally worked in the US and Canada as Agent, I can say without question that you will have a much better experience with Best Buy in the States.
The people are the only reason I would ever stay working at a Best Buy for any length of time, as management definitely doesn't care about their own company core values (Eg. Unleashing the power of our people, etc.) as they post the five values of renew blue and embrace the only one that is important to this company any more - Increase return on invested capital. While I understand a company needs to keep afloat, but if you give employees full access to a stores P&L don't be surprised if they start questioning some of the budgetary management. There are reports available to all employees, even reports regarding turn-over rates, lots of transparency on their systems but its all monitored. Anything and everything is recorded to be used against you, do not use their mobile apps.
I could go on and on, but honestly - do yourself a favor and treat any opportunity here as a temporary one, as the glass ceiling can be closer than you'd think and your worth more to a better company.
Management, deception and revolving door management, no job stability.
