Interview preparation tips for other job seekers - The overall selection process is going to be tough and interviews of this company are very difficult to crack. So make sure your concepts are clear the assignment that you have been given must not be copied from the internet because their back and team truly checks the assignment, and if anything is matched from the internet, they immediately reject you. You will be expected to make real time changes in the assignment that you have made along with properly explaining the logic of your code during the interview. So make sure whatever role you are applying to your concepts. Should be clear and make sure you read the job description as inside the job description. Many technologies are mentioned And there might be questions asked about those technologies during the interview for an example during my data scientist role tech technologies like AWS, Google cloud platform, docker, python, SQL. These technology related questions were asked and my project was based on natural language processing that was given in the assignment was supposed to make live changes during the interview. They asked me to add few features, modifying the data inside a column, removing stop words, adding few more features, etc.
