tips on assessment interview

[2512BC]

Hi my son has an interview coming up customer service advisor for a leading entertainment company - (no previous office experience)

group discussion, face to face interview and role play. lasts about 3 hours - how should he prepare ? what questions should he be ready for and what are interviewers looking for in group discussion, face face interview and role play? He has got through the online assessment and. Telephone interview - and this is the final stage - he has experience as sales assistant for past 5 years while at college and Uni. Thank s
