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 had only a week before my Revolut case interview and was feeling highly overwhelmed. Within our first session Mariana was able to give me a clear structure to understand the flow of the case and how to communicate well with the interviewer. Highly recommended!

Mariana was extremely helpful and an exceptional coach. She explained the structure and core principles of Revolut’s problem-solving interview with clarity and attention to detail. She also shared valuable resources that helped me deepen and strengthen my skills. I truly appreciated her patience and consistently supportive attitude throughout our sessions, as well as her personalized guidance based on my strengths and gaps. I’m very grateful for the opportunity to have sessions with Mariana and would highly recommend her to anyone preparing for interviews.
