Hi
If you are going to an assessment day you should wear business attire - suite and tie. But most importantly wear a warm smile.
The size of the foto at this stage is not so important - any passport size will be fine I think.
The photo size instructions I was given for the final interview were.
- Full length photo: 15cm x 10cm
- Passport size photo: 4,5cm x 3,5cm
I was instructed that I should wear a suite and tie in the photos.
I hope this helps you and others.
