在次请问

今天我收到回信了，果然是秘书打来的，他给我留下了他的电话号码，又说下个星期二晚上还会和我打电话联系，是询问有关“background information on who you are, financials etc"。 请问这是什么意思？我要做什么准备呢？是我主动打过去好，还是等着他打来？谢谢各位了！

Just wait for them to call u at the time reserved .
attention: 6 hrs time difference now(summer time)
maybe the secretary is going to know some further information which is not stated clearly in ur CV u sent to them before. Or, having been satisfied with ur research background, they indeed want to test ur english level,
:)
take it easy, good luck!

Thanks a lot!
