Since you are only just starting out, it is highly likely that you might end up working as a Data Analyst first and for a long time. The thing about Data Science is that it requires rigorous training and practice on real-time projects. And Google being Google, will not settle for anything less. So, you should understand that they are the least likely to fall for inexperienced candidates. So, I would highly recommend you to spend as much time on projects as you can and refine your portfolio so that you can showcase all your work when the time comes.
There are also many blogs that explain the Google interview process for the Data Scientist profile. So, you can go through those to get an idea. Google typically asks for proficiency in a few languages among the following: Python, SQL, R, Julia, Matlab, or Mathematica. You will also do well to familiarize yourself with C++ or Java.
