Hi. So I'm not sure anyone can answer this with a high level of certainty but I looked back to my experience last year to hopefully give you some helpful information with a historical context. Remember, this was last year and a lot changes from year to year so it really is anyone's guess.
Last Year, I received a bulk of my interview invites mid July (July 7-July 16th) and received my last interview invite on July 29.
I remember from my time researching these threads CWRU can reach out as late as early Fall (September maybe?) for an interview invite. I did not get invited to CWRU so I can't say when they sent out the invites last year.
I guess this is a long way of saying if you don't hear anything by august it may not be looking good.
I Hope this helps remove some uncertainty for some. Good luck all. try to stay patient.
Thanks for the update! It's good to remember that we're closer to the beginning than the end, even with interviews starting to get released.
