Halo Service Solutions Graduate Program interview questions

Applied online, initial screening call and then an extended delay before 10-minute call with MD to discuss the potential commute. Invited to in-person interview with two directors as MD was unavailable. There seemed to be no pre-planned questions, working through my CV and asking about each part. I was asked if I had "actually" sat my A-levels. Interestingly they voiced concerns at the end of the interview so I had a chance to respond. The rejection email was generic and not related to my interview.

Friendly interviewer. Asked about oneself, understanding of a product, and relocation to the place to work. Also about the roles in university. And which part of the role in of most interest
