First I applied via employee referral. Then I had an initial screening call which was very positive.
I explicitly thanked the recruiter for giving me a concrete timeline in which I would hear from her, whether or not I got the position. She told me I should hear back in about two weeks.
After two weeks went by, I sent her an email to check in. It's the summer so I understand that things are slow, people are on vacation, etc. She apologized for the slowness and told me I should be hearing back about potentially getting a second interview "soon."
Then another month elapsed. I sent her another email to ask for an update. Radio silence. It has now been two additional weeks since I emailed her and I have received no response, not even an OOO autoresponder.
