About

Machine Learning practitioner with 10+ years of experience scaling data systems at top-tier Silicon Valley companies. I’ve led impactful projects across Machine Learning, Recommender Systems, and large-scale infrastructure, and have been a people manager for over seven years. I actively interview ML Engineers and Engineering Managers, giving me a sharp lens into what top companies look for.

I’m happy to support you with:
- Resume reviews
- Mock interviews: system design, ML design, behavioral, and Engineering Manager
- Presentation rehearsals
- Role-playing critical conversations (e.g., asking for a raise or promotion)
- Career transitions: into management or into Machine Learning
- Career growth topics that matter to you (e.g., goal setting, project planning)
- Deep dives into ML technical topics of interest

Whether you're preparing for your next big opportunity or navigating a career pivot, I’ll meet you where you are and help you move forward with clarity and confidence.

I was glad that I had several calls with Xun. She managed to prepare me for a behavioural and system design interview at a big tech company using just a few sessions (offer received!). She was very engaged in conversation, and her comments and advice were always exact and understandable. I would highly recommend Xun and hope to speak with her again later during my career development

I had unsuccessful interviews with big tech companies a few months before. I decided that I need some additional checks and advice for another opportunity with Meta. I had a recommendation about Xun from my former colleague and I have no doubts now that this collaboration was very helpful for me too. I had three calls with Xun, mostly for mock interviews (2 ML system design and 1 behavioural). She gives you very clear comments about things that you would never think of on your own. It could be something obvious or very thoughtful and deep, but it would be very helpful, and you would understand what you need to do to fix it. Xun was always very polite and easy to communicate with. As a result of this mentorship, I was able to pass the Meta bar for the SWE (ML) position. I really enjoyed working with Xun! Don't hesitate, this could be a turning point in your career!

I highly recommend Xun Tang as a mentor or collaborator in machine learning and technical interview preparation. While preparing for competitive FAANG interviews, Xun’s guidance significantly improved both my confidence and performance. From day one, Xun approached our sessions with exceptional structure and insight distilling complex topics ranging from modelling to system design into focused, interview-relevant content while simulating real interviews and offering precise, actionable feedback. Beyond technical skill, what stood out to me was Xun’s commitment to my success. They consistently went above and beyond, tailoring our sessions to my specific goals and weaknesses, and always bringing a thoughtful and encouraging presence. Their support gave me not just the knowledge I needed, but the confidence and mindset to succeed under pressure. I wholeheartedly recommend Xun Tang to any individual looking for a world-class ML mentor and coach. Their expertise and character are of the highest caliber.

I reached out to Xun for a mock ML design interview, and it was fantastic! She came extremely well prepared with a question directly relevant to the company I’m interviewing with. Her feedback was thorough, actionable, and helped me spot gaps in my knowledge. I'd highly recommend her to anyone looking for ML mock interviews of any kind!
