I helped candidates secured offers at McKinsey, Bain, BCG, Kearney, Revolut, Eli Lilly and others. DM me for a free 20min 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.

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, BCG, Bain, JP Morgan, Morgan Stanley, Accenture, Revolut, 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.

Interview Coaching
Mariana is absolutely great coach - the best I ever worked with! We had 4 sessions back to back over 3 days, given short timeline I had before the interview and thanks to her, I was able to build at least the minimum required skills pretty much from scratch. Very thorough, in depth sessions, focused on fixing the weaknesses. The materials, hints and advise I got from her were absolutely invaluable. Strongly recommend taking at least several sessions with Mariana for your preparation! Many thanks, Mariana!
