Minimal case interview experience + weak mental math. Can I still do well?
I have a first-round interview for experienced hires next week July 10th that includes a live case interview and a chatbot case. I'm currently a senior consultant, but my experience is almost entirely in the public sector, so I haven't had much exposure to traditional business casing. I also came from a healthcare background before consulting. I've only done a couple of practice case before, and honestly, the math is what I'm most nervous about. Mental math has never been my strong suit, and I'm worried it'll trip me up during the interview.
For anyone who was in a similar position, what helped you get up to speed quickly? Any tips for handling the math portion, structuring cases, or preparing in the week leading up to the interview would be greatly appreciated. I have been studying everyday all day since getting the invite on thursday, but I didn't expect to actually get an interview offer when I applied.
