Students will get a basic idea of the course contents. Problems will be solved using Python and SQLITE3 in Python. If students do not have anaconda and jupyter notebooks, it will need to be installed to work on the problems in this course. Go to the Anaconda website.
I give an overview of the types of interview questions asked in a data science interview.
Part 1 and Part 2 Python Review of Programming concepts useful for live coding interviews.
An SQL review (Part 1 and Part 2) is given by constructing queries to answer questions that can be asked about the contents of the tables.
Part I and Part II of Machine Learning covers machine learning concepts that are most likely to be covered in interviews
This interview was conducted live with a fintech platform that helps small businesses with financing.
This question was for a bitcoin trading firm. The question was asked on Hacker rank.
This was a live interview on Coderpad with a big tech/FAANG company. It was for a Product Data Scientist position.
A take home that was asked by an Insurance Tech Start Up. The question revolves around renters who default.
This lectures goes through one possible method of solving the take home problem. Students are encouraged to critically analyze the solution, and see if they can make improvements upon the analysis.
This was another take home exam. This time for a Food and Delivery Company. Time Series Analysis, namely the ARIMA model is used to build forecasts. Students will be introduced to ARIMA and given a step by step solution that got me to the next rounds. Students are expected to go through the notebook, and make improvements.
This was a timed take home. It involved bitcoin analysis.
Breaking into the field of data science requires a strong grasp of technical skills and a strategic approach to the interview process. This course is designed to equip aspiring data scientists with the knowledge and practice needed to succeed in job interviews across various industries, including Big Tech, fintech, Food and Delivery, and more.
Through a combination of real-world interview questions, hands-on coding exercises, and case studies, students will develop expertise in Python, SQL, machine learning, and data analysis. The course covers different types of interviews, such as take-home assignments, live coding challenges, and system design. Students will gain insights into data science hiring trends, organizational roles, and the expectations of employers at different experience levels.
Key topics include data preprocessing, exploratory data analysis, feature engineering, model evaluation, and machine learning algorithms commonly tested in interviews. Students will also learn how to prepare for recruiter screenings, and effectively communicate technical concepts during interviews. The course also provides strategies for tackling time-constrained coding challenges and problem-solving assessments.
By the end of this course, students will have the confidence and skills necessary to tackle technical interviews, showcase their problem-solving abilities, and secure data science roles in a competitive job market. Additionally, students will understand industry-specific nuances and best practices for structuring data-driven solutions during interviews.
