Ah don’t feel too disheartened but I honestly know the feeling😔 I did exactly the same in my interview- the case study threw me and the girl from HR had to prompt me twice 🙃 it might feel a bit rubbish now but you’re not the only one so don’t lose faith!Thanks all - really nice messages. Tbh i know i didn't smash it as it threw me off so bad he basically had to tell me the answers oh well i'll get over it but think its just so luck based when they ask random questions in interviews rather than having set questions for everyone !!
