The significant growth of data science has been realized as the mainstay of decision-making in most industries; MNCs are no exception. Organizations depend on data scientists who are able to analyze wide ranges of data and bring out meaningful insights that will lead to strategic business decisions. Landing a data science job at an MNC might be rewarding but also could open many doors toward growth, learning, and innovation. The ways to such a position, however, are competitive and challenging. This will be an all-inclusive guide to steps that have to be taken in order to successfully land the data science job in an MNC—right from building a strong foundation in data science skills to sailing through the job application process.
Though a formal education is not always a very strict requirement, a strong educational background will largely improve prospects. Many MNCs require a minimum of a bachelor's degree in the related field of study in computer science, statistics, mathematics, engineering, or information technology. Further advanced qualifications such as Master's or Ph.D. in data science or related fields make a person highly qualified.

AWS Redshift/Google BigQuery: Cloud-based data warehousing solutions.
Besides technical skills, the requirements also include soft skills which are of prime importance for a data scientist. These are:
Communication: To express complex technical ideas to non-technical stakeholders.
Problem Solving: Logical thinking, creativeness facing problems in data.
Collaboration: Interact with any cross-functional teams of business analysts, engineers, and product managers.
This can be done through internships or full-time entry-level jobs which will help a student gain practical experience and professional networking. Search for internship or entry-level job opportunities within finance, healthcare, e-commerce, or technology sectors. During the internship, primary things to focus on are technical skills development, in-depth understanding of business problems, and how to effectively communicate insights.
Build a portfolio that conveys to potential employers what you can do. That means working through real-world datasets, competing in Kaggle competitions, and working on open-source projects. Your portfolio has to showcase how you have honed skills in tending to almost all facets of data science: cleaning, exploration, modelling, and visualization. Core Projects to include:
Data Analysis: Take a dataset and find the trends, patterns, or insights within.
Machine Learning Projects: Build prediction models and analyse their performances.
Data Visualization Projects: Developing dashboards or other interactive visualizations to effectively show the discoveries.
By participating in hackathons and competitions, you will be exposed to real-world problems, learn to develop your skills, and network with industry professionals. Kaggle, DrivenData, and Zindi are organizations that run data science competitions with cash prizes and recognition among other current winners.
A professional network can help the job seeker get a feel for opportunities and the overview of the industry. Attend conferences, workshops, and meetups on data science to network with peers and potential employers. One may also utilize the power of LinkedIn for this purpose, since it is a great forum to expand one's network and share skills and experience.
Association membership to professional organizations like the Data Science Association or the International Association for Statistical Computing allows for access to resources, events, and a community of peers. They hold webinars, workshops, and certification programs from time to time in order to refresh your knowledge with industry trends and progress.
Informational interviews with industry professionals can be very resourceful in knowing more about the industry, the culture of companies, and the roles undertaken. You can contact alumni, people within your industry network, or connect with contacts on LinkedIn to request an informal discussion regarding their experiences and career paths.
It is usually your resume that makes the first impression on any potential employer. Make sure it is neat, brief, and relevant to the target job. Bring out your technical experience, qualifications, and projects that are relevant for the job target. Use action verbs and quantify your achievements wherever possible.
Objective Statement: Statement of career goals and description of what an applicant has to offer.
Education: Include your degrees, certifications, and relevant coursework.
Experience: Work experience, internships, and relevant projects.
Skills: Technical skills, programming languages, and tools.
Projects: Key Projects that attest your expertise.
Certifications: Relevant certificates acquired.
An effective cover letter helps you to be noticed beyond other applicants. It should therefore be written with respect towards the position and the company, clearly bringing out your passion and suitability for the job. Bring out your relevant work experience, qualifications, and accomplishments. Clarify why you are joining the company and what you can do for them.
Your LinkedIn profile serves as the expansion of your professional brand. Be sure to update it with a professional photo, a headline that captures eyeballs, and a summary that gets into the nitty-gritty of experience and skills in the realm of data science. Use important data science keywords to ensure your profile shows up when someone searches for them. Attach links to your portfolio, GitHub, or other projects relevant to the domain.
