I'm the #1 coach for Revolut, for Problem Solving and Bar Raiser interviews.

My clients currently achieve a 60% pass rate in the Problem Solving interview, compared with ~16% in the industry (UK benchmark).

* Clarification: You may see coaches for McKinsey, Bain and BCG with a +90% passing rate. That's mainly due to the fact that MBB candidates have months to prepare, whereas at Revolut most have a week or two. 

About me:
- Former Product Ops Manager at Nubank, the largest fintech in LATAM (+100M users), ranked among the top 5% of performers in my field.  

- Responsible for Problem-Solving internal training at Nubank, equipping teams with the tools and techniques to tackle complex challenges.  

- Part of Nubank’s recruiting workforce, where I have conducted case (Problem Solving) interviews to several candidates for Product Ops (equivalent to Strategy and Ops position) and Product Management positions. 

Before that:
- First place among 3,000+ competitors in the McKinsey Impact Experience, a national case competition 

- Former McKinsey consultant and internal case interview faculty, supporting new candidates and delivering training to help them succeed in their interviews.


- McKinsey’s recruitment champion for South Brazil, leading efforts to attract top talent to the firm.

Interview Coaching
I recently had a few coaching sessions with Mariana ahead of my problem-solving interview. Mariana was extremely helpful, supporting me with the style and structure of the interview, and working through multiple case study examples with me. She also provided materials on how best to structure and analyze cases, ask the right questions, and apply various techniques to perform well under pressure. I’m pleased to say I was successful and have progressed to the final stage.
