3 stages of questions including in a roleplay after initially having to take an hour long questionnaire online only to be turned away for not passing stage 2, ridiculous interview process for a simple job

The application process was straight enough. I applied online followed by questionnaire which lasted around 30 ish minutes. The questionnaire was mainly about how would you act in different situations with customers. The results were immediate and then had to select the date for interview. The interview was of two stages: Role play followed by an interview with the manager. In the role play, I was given a list of the menswear (could be anything even foods, ladies wear) like their descriptions, availability of different colors, latest promotions, current stock level etc. I had 10 minutes to have a look about all of them and to makes notes in a paper that they provided.The assessor then comes as a customer and asks questions just like a customer who is unable to find something and help them. The success of role play is being calm, welcoming and smiling. It is essential to state the promotional offers and also help a customer (assessor) by saying that a product can be ordered online if it is out of stock. These are the key things what they look for. If the role play stage is cleared, then it is an interview with the manager. Since, it was very busy times during Christmas, I didn't have a formal interview. I was just asked about my availability and if I had any experience.
