Ask HN: Long notification period normal?

Hi there,

"recently", I have applied for an internship at IBM Research and Microsoft Research. In fact, almost two months have already passed without any notification whatsoever; one of the jobs I applied for has been taken off the available jobs platform, and I am not sure what to make of it. Since there are many other PhD students on HN, I thought I'd ask people here about their experience with application procedures for those labs. Is this kind of behavior normal, or should I start looking somewhere else?

Many thanks for any information!
