If I get an offer for next summer and I don't choose to take it, is it possible to not have to interview again for next next summer and go straight to host-matching again next year around this time? Has anybody done this?
How did you already get an offer? The summer process just opened up.
I don't have an offer, I'm still in the process but I'm wondering if there is any point in being in the process if I already signed another offer
You can always sign the offer and renege if you passed host matching later. Depends on what company and if you want to renege or not
Not possible unfortunately. You have to reinterview. It is possible if it's only for 1 semester
