Few months ago I applied for a job within a global company, the HR person for that position sent me an email few days later to set up an interview over the phone, interview went well, HR person asked me when I could go for an interview with the manager, I left it open to their discretion. But HR person never responded back, I sent a follow up email and it was just ignored. I have that person in my LinkedIn contacts and sees my messages, but not response, just ignoring. The job still open in many web pages. What may went wrong????
