Dan Lee

Data Scientist@Google (& Ex-PayPal)

Frustrated about data science and ML engineer interviews? As someone who had been a candidate myself, I share your frustration. That’s why I created – a one-stop shop for preparing for data science and ML engineer interviews. After working five years as a data scientists across three companies – Booz Allen Hamilton, PayPal and Google, I have curated top-notch interview content designed to accelerate your progress in interviews at top companies. Work with me and land your dream role =D

How It Works

Key steps to preparing for an interview with an expert coach.

Step 1 - Setup

After you purchased sessions, an interviewer will schedule an appointment and personalize a mock interview based on the company, team, role and round you are interviewing for.

You can design it however you want. For instance, Do you want a phone-screen or on-site based on Facebook’s Product DS role? I can design a session for you that helped candidates ace the Facebook interview. 

Step 2 - Live Session

Each session is 60-minutes with 40 minutes of questions and 20 minutes of feedbacks from an instructor who worked as a data scientist at a FAANG company. The feedback consists of solution + assessment + rubric with ratings.

The session will be recorded for quality assurance and given to you for you to review.

Step 3 - Rubric

After the mock interview, the interviewer will send you a grading rubric with ratings on attributes assessed on the round. This simulates the actual post-interview process at top companies such as Facebook and Google. 

In addition, the interviewer will forward tips that can be helpful for your prep as you continue your journey towards acing your upcoming interviews.  


You will have a 3-month access to all the courses available in the monthly subscription. The courses include AB testing, SQL,  statistics & ML question bank, mock interview videos, and DS case problems.

The coach will review your resume and provide you with pointers that will enhance your resume for recruitment.

Yes,  send an email to He will get back to you within 1 to 3 business days.

Once you purchase one of the coaching services, Dan will send you an email with Calendly for you to book a session with him. The coaching hours are from 3 to 5 P.M. PST M-Th, and 2 to 4 P.M. PST on Fridays. If you need to meet outside of those regular coaching hours, that can be arranged.
