Similar situation, similar dates, only absolutely no news whatsoever since the signing of the offer in may (besides confirmtion of the acceptance). No replies to e-mails either
.
A bit disappointed, at least a little "we know you´re still there, give us two or three more months pls" would make a huge differnce in perception.
Meanwhile refusing less tempting offers, hopefully not regretting it later on. Anyway... Anyone knows if an expired IR is a problem upon joining?
