Folks who were in middle of interviews, but the position got filled/ put on hold, how did it go? Did the HR contact you again for similar position?

Yes, it happened to me in the case of offcampus hiring by Zeta during my college days. I was being interviewed for an intern role, which got filled. Later I got a call for an FTE role.

Re-Opened after a week in a different team then proceeded with the last round.

Yes, 4 months later that position opened up 😂

Not only in the middle but it happened to me even after sharing pre offer docs

Nope. Full ghost

No, never
