My son has applied to Cambridge University and the application says international student interviews will take place in late November. He has yet to hear if he will get an interview. Should he be worried? Does Cambridge notify students if they decline to interview them?
Your son will definitely get a formal notice of the outcome of his application, whether or not he is being invited to interview.
There is another poster on CC who has been notified of a NY interview offer- but I wouldn’t panic, as interview invitations go out by subject and/or college (depending on the subject). The same is true for offers: they aren’t all released at one time.
