Hey all! I'm offering discounted coaching since I just started coaching again in May. I was an extremely active coach in 2022 on Leland and several other platforms before McKinsey--feel free to check my reviews on Leland. I have coached 75+ to consulting offers and 50+ to MBB during my time as a mentor at Wharton's consulting club and in my time coaching outside of bschool. I have extensive experience working with applicants currently in school (including non-target) and experienced hires. Consulting recruiting can seem daunting, but it’s surprisingly formulaic. While it’s not easy, I’m here to help make the process easier (and hopefully more fun) and maximize your chances at an offer. While I am an MBB specialist, I also have experience with the interview process of every other large consulting firm and a handful of boutiques, so happy to help with whatever firms you're targeting. Feel free to ask questions or request any type of help, but these are usually the 3 areas I spend my time coaching: 1. Acing the case interview (strategy is generalizable across firms--areas of prep are case starts, frameworking, brainstorming, case math, case flow, recommendations, etc.). This is 75% of my consulting coaching and I've been coaching it for thousands of hours since 2020. 2. Impressing in the behavioral (very firm specific--McKinsey's PEI is the most infamous and I'm a specialist at this). On my McKinsey interviews, I got glowing praise for showing both emotional intelligence and strongly developed stories on my PEIs. 3. Landing an interview (networking, getting referrals, getting on the firm's radar). Whether you're an experienced hire or applying from school, this process is crucial.

About John
Just rejoined the coaching world after 3 years as a consultant at McKinsey! Offering discounted services for several weeks as I build up my student base again. I offer 3 primary services: 1. McKinsey/MBB specialist offering case interview prep (coached 50+ students to MBB offers); ALSO full preparation on everything from resume/networking to behavioral 2. MBA resume, essay, and interview coaching/review 3. GRE/SAT tutor with years of tutoring experience (NO LONGER OFFERED!) But I'm always happy to cater to anything you need help with! I love teaching and dreamt of being a teacher when I was younger, but unfortunately teachers are under-appreciated and underpaid in the US, so I went a different route. After quitting McKinsey, I declined several jobs to focus full-time on coaching. Feel free to message me with any questions, and I look forward to helping you land your dream job or MBA/graduate school offer! As a Wharton MBA student, I was extremely active in the Wharton Consulting Club and coached over 30 students to consulting offers. I'm also a former writer and psychology researcher, so I know exactly how to deliver and crush behavioral interviews, especially McKinsey's PEI. Since Wharton, I have also tutored an additional 50+ students in all aspects of consulting. I'm known for my rigorous/methodical casing approach and feedback and my devotion to my students (check my reviews on here!). During and before business school, I also helped students with MBA admissions, and I served in the Student Admissions Program while at Wharton. Additionally, I tutored the SAT and GRE, receiving a 170/170 quant, 169/170 verbal, and 5.5/6.0 analytical writing.
