HELP!! Interest Rate Derivatives Interview

Hello everyone,
I have recently been shortlisted for an interview with the hiring managers for an intership at a local (Singaporean) bank. As the title suggests, I need some help/tips regarding the interview which is in 5 days.

the job description is as such:
1) Support traders in doing daily cash-flow and reports generations

2) Creating Radar report(what's that?) to assist desk head and traders to pin point turning points in macro environment

3) Consolidating spreadsheet for desk usage in pricing internal and external customers

Programming skills eg: VBA and C++ required.

Previously they had shortlisted us by asking us to submit a report on some technical qns.

Any tips on what I should specifically prepare for would be highly welcome (I'm planning to refresh my coding, product knowledge stuff as well as the latest market news)

thanks!
