Sollicitatievraag bij Harrods

I don't want to say which department I applied for specifically, but I will make an equivalent example. Say that I applied to sell small kitchen appliances, the interview question was worded like "roleplay selling this specific model/brand of toaster to a customer". You would be at a disadvantage if you didn't already have that product knowledge and I did not. It's preposterous to expect pre-existing knowledge for what was basically an entry level job. Product knowledge should be taught on the job.
