Hi everyone! I’m feeling pretty stressed about my upcoming consulting interviews with top firms and could use some advice on making the most of my remaining prep time.
I’m an economics major with consulting interviews coming up in early August. So far I’ve done about 17 practice cases and have roughly 3 weeks left to get ready. I’m also working a full-time internship right now which makes it tough to find study time.
I’m worried because I don’t feel like I’m improving much despite the practice. Coming from a non-business background, the whole case interview thing doesn’t come naturally to me. Most other candidates I know have already done 40+ practice cases.
Here are my main problem areas:
Speaking Skills: I get tongue-tied and ramble a lot during cases. My practice sessions often run way over 30 minutes because I can’t get to the point quickly.
Math Under Pressure: I’m fine with calculations when I can work quietly on paper, but doing mental math while talking out loud is really hard for me. I make mistakes and the interviewer has to help me get back on track.
Data Analysis: When they show me charts or numbers, I struggle to figure out what it means for the overall problem. I have trouble coming up with good insights or next steps.
Anxiety: My nerves definitely hurt my performance and cause me to freeze up during cases.
I want to get good enough to confidently lead the conversation and come up with creative solutions. Any suggestions for how to use these next few weeks effectively? I’m thinking I need a mix of solo practice and live cases but not sure what the best approach is.
I was in the same boat last year - 2 weeks to prep while doing my internship. Voice memos saved me. I’d record myself explaining business concepts during my commute, walking through frameworks out loud. Super awkward at first, but it fixed that whole talking-while-thinking problem. For math anxiety, I did practice problems with music or background noise to mimic interview stress. Game changer was realizing interviewers care more about your thought process than getting everything right. Once I started talking through my reasoning (even when I wasn’t sure), my performance shot up. The nerves don’t disappear, but thinking of it as a business chat instead of a test made it way easier.
the math section gets everyone, including MBA students. I started using my phone calculator but would verbally walk through each step before punching numbers. felt ridiculous at first, but within a week I was doing it naturally during actual cases. for data interpretation - skip the prep books and work with real earnings reports instead. you’ll pick up on how business data actually tells a story way faster than with fake practice materials.
3 weeks is tight but doable if you focus. Don’t count practice cases - quality over quantity. You’re overthinking instead of being direct and structured. Try giving yourself 30-second summaries after each section to stop rambling. For math anxiety, practice calculations while talking out loud - sounds weird but it works.
Most people bomb these anyway, so don’t stress about being perfect. Just be clear and confident with your approach.
Skip more case practice - fix your fundamentals first. Record yourself doing solo cases and time each section. Most people who ramble don’t structure their thoughts before speaking. Take 10-15 seconds to organize your response before you talk. For mental math, start calculating out loud during daily stuff - tips, grocery totals, whatever. This builds the muscle memory you need. For data interpretation, focus on the ‘so what’ factor. When you see a chart, immediately ask what business decision this data supports. Consulting firms get thousands of applications, but they want clear thinking under pressure, not perfection. Your econ background gives you quant skills that many people struggle with. Use frameworks like profitability trees or market entry analysis as your safety net when you’re lost. Three weeks of focused practice on these specific weaknesses beats rushing through more cases.
Your timeline works if you stay focused. Since anxiety and pressure are your main issues, do mock interviews with strangers - not friends or classmates. This creates real pressure and gets you used to the stress. For data interpretation, practice explaining charts from Harvard Business Review or McKinsey Insights every day. You’ll start recognizing common business patterns. For math, build your own toolkit of quick calculation tricks and practice them while commuting or doing boring stuff. Here’s what most people miss: consulting interviews test how you think, not what you know. Develop one problem-solving framework you can use for any case topic. Your economics background is actually an advantage - you’ve got analytical skills that business majors often lack. Record yourself doing practice cases alone to catch when you ramble. This self-awareness will help you improve faster than just doing more cases.
