You're right, interviews come before inductions. Inductions go for a lot longer than 1 hour, usually 7-9 hours, so I think you'll probably just be going for an interview.
The group interview tests your teamwork skills. They out you in little groups to test communication skills, for example they'll give you a situation and as a group you have to prioritise tasks, then one group member is appointed to address the whole interview with their teams decisions.
They might get you to do a reading test, where you have to match a number (eg 57328) in a multiple choice sequence. Its timed though, so the idea is to get as many correct answers as possible.
I didn't have a one on one interview, but from what I know they just ask you simple questions like "Why do you want the job?", "what is your availability?", "why did you apply for woolworths?". This stage is pretty hard to stuff up, but I know people who have. If you look presentable, and speak well, you'll be fine.
If you're successful here THEN you'll be invited to induction. As you mentioned, heaps of videos, manuals to read, etc. Once you get to an induction you have the job - its a paid training session.
I hope everything works out
Good Luck!
