Over the past few months, as I navigated my journey towards an MLE role, Xun has been a cornerstone of my preparation. Her mentoring style is both comprehensive and insightful, covering a wide range of topics from standard system design and behavioral aspects to the intricacies of ML system design. What sets Xun apart is her ability to use her extensive experience to identify and target specific areas where I needed improvement. There have been many times where a mock interview with Xun has lead to an "aha" moment of understanding for me. Xun doesn't just identify areas for improvement; she offers highly actionable feedback that's easy to implement. Her suggestions are always clear, precise, and tailored to my unique learning style, which has made all the difference. It's rare to find a mentor who combines such deep expertise with the ability to impart knowledge effectively, and I'm incredibly grateful for her guidance and support

Xun helped me a lot in preparing for the ML system design for the interview in Meta. We walked through different interview problems, and she showed me my weaknesses and gave me recommendations on what I should do better. I am impressed with Xun's knowledge of ML system interviews, their understanding of problems and solutions, and the way how explains them. I would recommend working with Xun for everyone who would like to get an honest evaluation of their readiness for ML system interviews and improve their skills in that area.

Session: Mock Interview

I reached out to Xun for technical review on a presentation I plan to do. She gave me valuable feedback on the content and the material. Would definitely recommend.
