Just as important as demonstrating your technical proficiency is demonstrating your behavioral skills.

Problem-Solving Skills

When Google hires Data Scientists, problem-solving abilities are like superpowers. For a successful interview, you need to be ready for questions involving problem-solving and showcase your abilities using examples from the real world.

Suppose you are asked to evaluate an extensive large dataset, for instance. In that case, you might clarify how you handled missing values or outliers and used statistical techniques to derive insights from the data.

Therefore, you should work on presenting complex technical concepts in simple terms to demonstrate your ability to communicate. Furthermore, you must prepare for questions that test your communication abilities.

For instance, if you're expected to clarify an intricate Machine Learning technique to a non-technical person, you may simplify it and include cases from the real world to make it more relevant. You may present your ability to express technical concepts in this way successfully.

Follow-up and Feedback

Follow-up is crucial to demonstrate passion and maintain contact with the company after a Google interview.

Besides expressing your interest in the position, you may also thank the interviewer for their time. Sending updates on your professional life or relevant business news can also be a part of staying in touch.
