Working with Malena on 1:1 coaching for the product sense question was the best decision I have ever made. She helped me refine my frameworks by walking me step by step through the right questions to ask to arrive at the answer. She is an expert in the field and passionate about it. Even after the coaching sessions, she went above and beyond to make sure I fully understood how to structure my answers. Without her, I would not have landed an offer from Facebook. I would highly recommend Malena! She is the best!

At the beginning of my data science interviews, I had no idea how to handle product case questions. After spending over two months with over 50 mock interviews, I was able to speak confidently with a well-structured framework and hence ace all my product case interviews. The mock interview experience and the friendships you gain from the StellaPeers platform is super valuable! I highly recommend StellaPeers to any data scientist who wants to sharpen their product case interview skills.
