I've been dragged through this process a few times. In two cases I got a lot of enthusiasm from the recruiter and promised interviews with specific hiring managers. Then... nothing. No updates, no replies to my emails. In another instance I was brought in to interview and offered a job the next day. I had a job so I said I would put in my 2 weeks notice when I got the official offer. Then I waited, and waited,the recruiter kept shrugging at what was taking so long. Two weeks later the offer was rescinded to move the req to a different department. The recruiter assured me that they would follow up with the manager to let them know I was already chosen for the role. Then silence. I never got replies to my emails and just had to assume the process had stopped. They've jerked me around so many times I can't believe they hire anyone.
