Is performance at an assessment centre generally viewed holistically?
I had three interviews and felt two went well and one I struggled and wouldn’t say it was strong at all. Do you need to perform highly across all three interviews to have a chance or could the strength of the other two help my case?
I know it’s out of my hands now but really replaying the bad interview in my mind and want to know if there’s any indication that I’m still in with a shot?
It really is difficult to tell but I am sure it went better than you think. There have been assessment centres I have done last year which I thought went horribly and I ended up getting the offer in the end so I really would recommend not thinking about it. What you might consider bad, might not be perceived in the same way by your interviewers.
Additionally, remember that you have done everything in your power to succeed today and you are already so smart for even getting to this stage, I personally would be so proud of myself if I was you as many people cannot say to have been this lucky unfortunately.
The result is still not out so just think about how far you've come and how much you have learned through this process and I am sure you will be able to succeed in the end.
Generally, you would need to have impressed all your interviewers to a certain degree so this is important to bear in mind. Having said that, you never know what might have been interesting or appealing to one interviewer compared to another so I would say focus on the positive aspects of the situation and wait for the result which I am sure will be positive.
Good luck with your cycle!
