Gave the interview some weeks back, did not hear back and on asking too they don't reply, anyone from Palo Alto network have any clue what's happening? Did anyone else also face a similar situation with them ?
For what role ?
Don't listen to F5...they're hurting because they're losing talent to PANW :). That is strange. We recently migrated from Microsoft office to Gmail (a week or 2 ago) so maybe your emails are getting lost in some black hole? Sometimes I've seen recruiters take time off for a week or 2, maybe they didn't set up the automated "I'm away" email in Gmail, which should redirect you to another recruiter.
Why going to PA after Microsoft in first place ?
