About

Hi everyone, I have more than 8 years of experience in data science/analytics. Worked in several tech companies such as Meta and Tiktok. I have conducted 30+ interviews on data manipulation/coding, product sense and statistics. And also I have personally interviewed at dozens of companies as well. In addition to interview prep, I am also happy to do resume reviews and talk about data science work and career in general!

The coach gave a great instruction and feedback through the mock interview. He provided good case for mock and gave the feedback for the answer from a professional way. I really appreciate his great effort and help.
