Co-op Custom Team Member interview questions

I applied online and received an email to book an interview. So i arrived at the interview I was taken into room in the back by an employee and waited for the manager to call me. The manager came and took me into a room and carried out the interview , the interview was easy just basic questions asking about yourself and why you want to work there. However I believe the manager was very unprofessional when he first saw me he said " ya alright mate" and shook my hand and I felt like he was rushing through the questions. On the email it said the interview would last up to an hour, the interview only lasted 4 mins. Seriously a 4 minute interview I went into the room at 12 and was out the shop at 12:05. Overall was an easy interview.

Applied online, got an email to attend interview and then 1:1 took about 20 mins then left, took about 1 week for feedback and then they offered me the job
