Mariana Zarth

#1 Revolut Coach

I am a former Senior Product Ops Manager at Nubank, one of the world’s largest digital banks , where I led internal Problem Solving training and participated in recruiting efforts, conducting case interviews for Product and Strategy & Operations related roles. Prior to Nubank, I worked at McKinsey & Company, where I supported recruiting and candidate preparation for case interviews. I also ranked first among 3,000+ participants in the McKinsey national case competition. Over the past 1.5 years, I have used my Problem Solving and Case Interview expertise to coach dozens of candidates preparing for Revolut’s Problem Solving stage across multiple functions and geographies.

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.

Mariana coached me for both the Problem Solving and Bar Raiser rounds at Revolut for a senior role. I passed both rounds and Mariana was undoubtedly key in ensuring I performed to the best of my ability. Mariana provided very insightful and thorough coaching on what to expect at both stages and worked through practical examples with me as well as providing practice and detailed feedback on my answers. I went into both interviews feeling more confident and able to display the best of myself. Thank you!
