I went through a two-stage interview process. Both of the interviews had two interviewers each (one of whom is a Manager/senior and the other is an Assistant. They will ask a lot of questions that may come across as they are experts, but don't be fooled by this - as once you join the organisation, you will realise that there are no set processes, the managers are incapable of doing their job, HR cannot provide adequate support as they themselves are not qualified.
