A B Mauri Food interview questions

Got a proper schedule for the interview from the consultant and received the status as well. The overall process was good and well-managed. The interaction went well but details JD was not shared by the consultant.

The interview started well. They asked about my previous role and responsibilities. Then they asked about CSR which i answered in as much as i as a buyer is involved but they asked in details to which i said there is a CSR department that dealt with that aspect. Then they asked about health and safety to which i answered, and when on to ask about PPE asking me to explain what PPE stands for. I thought I'm back in kindergarten. I've been working for more than 20 years and they think of asking me meaning of PPE?
