Hands-on support
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 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!

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.

Xun is a very responsive and responsible mentor! I like that she was very honest about my situation after we went through my work experience, and yet she was very encouraging. I did a project deep dive with her, which was very helpful as she not only challenged me deeply technically, but also spent time walking me through my answers and what interviewers will be looking for. very professional. She also offers other kinds of other mock interviews, including ML knowledge and MLSD etc. overall it's been truly a great experience working with her! I would highly recommend!
