I helped candidates secure offers at Revolut, McKinsey, Kearney, Eli Lilly and more. DM me for a free 15min alignment call.

Hello and welcome to my profile!

Since the beginning of my career I have coached and mentored candidates that wanted to join consulting or tech industries.

Helping others achieve what I have achieved and seeing them succeed really energized me! 

After McKinsey, I continued to contribute to recruiting initiatives at Nubank, the largest Fintech of LatAM where I worked as a Product Operations Manager. 

I have given more than 200+ mock sessions and helped candidates with limited experience and unconventional backgrounds to join highly selective processes (for those that hired my CV service) or getting a job offer (for those that choose case and fit interview) in companies like McKinsey, Revolut, BCG, Bain, JP Morgan, Morgan Stanley, Accenture, among others.

I believe almost anyone can become a consultant, if this person put the necessary effort into it

Before succeeding in my own consulting interviews, I had to improve my structuring, math AND communication skills - yes, I was all over the place. 

After putting in the hard work, these areas became strengths that continue to serve me in real life.

If I could develop these skills and land an offer at McKinsey, you can, too. 

I’m here to guide you every step of the way with a detailed, results-driven approach.

About me:
- 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. 

 
- Former Product Ops Manager at Nubank, the largest fintech in LATAM, 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 interviews to several new candidates for Product Ops and Product Management positions.

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.

Mariana helped me pass my Revolut Problem Solving interview at a senior level! She was incredibly helpful. I was able to understand exactly what I needed to focus on, what my strengths were and the areas I needed to improve. She shared useful resources and leaned on her experience helping others in this same interview to enable me to pass. I can’t recommend her enough. Thank you Mariana!
