Hello sakti,

You have enough time for personal interview and micro presentation,

If you really want to excel and crack the interview,

You need to work on your aptitude, communication and your knowledge.

It will be better if you first find out some tutorials on the internet to gather some information about latest questions asked.

Follow some good psychological magazines and read out some research papers related to your field.

They always help you out, also study some case studies,

Most of the time interviewers will give you some case study to solve, hence practice them before the exams.

Take some fresh topics for your micro presentation and read about your material so that you can explain it in depth.

I hope it helps

Best of luck for your exam
