I was part of a large-scale group interview for offices across multiple boroughs, and then was moved forward to one office. (I'm not sure if this was how it worked for everyone or not.) I went on to interview with that office 3 more times over multiple months, and they never got back to me. When I reached back out to larger HR to ask about jobs in other boroughs, they said the one I had interviewed would be in touch soon. This repeated over months. I felt strung along, and barred from potential opportunities due to one team's failure to communicate. Frustrating!
