PwC Senior Manager interview questions

I went through two rounds of interview, at which point I was told the firm had frozen hiring but they might be in touch in future to continue the process. The HR hiring manager didn’t turn up to the scheduled call four times to pass on this news, and when I finally got on the phone with them they did not give any feedback from the second interview (despite repeatedly promising it). This was for a fairly senior position and I was gobsmacked that PwC would be so poorly organised, unaware of their hiring needs and so unwilling or unable to give basic feedback to candidates. Will be giving a wide berth in future.
