Frequently Asked Question (FAQ):
How to get successful in the filed of Data Science and Machine Learning, what is the probability of getting the job?
Few tips for you: Remember, you need to create your profile. I suggest, if you don’t have, create your GitHub account and upload all of your work there. As a data scientist, one of the key thing is reporting based on your findings. This course is an excellent jump-off to get into this rewarding career. After finished each project / section, create a report and present conclusions. Attach the report to each project in your Github account. You are most welcome to reference this course in your report, this might be helpful. Please don’t put the course material (the folder which came with this course) in your Github, create your own stuff (don’t worry even if they are similar), everything should go through your hands. I have seen that the blog posts are also helpful in creating your profile and to make good connections. Regarding job, there are more jobs in the market than the available professionals in this field. This course will land you in the interview, success is on your efforts and hard-work. Practice is a key and there are tons of datasets available to practice your skills. Keep yourself motivated, a great career is waiting for you!

Brief overview of Data around us:
According to IBM, we create 2.5 Quintillion bytes of data daily and 90% of the existing data in the world today, has been created in the last two years alone. Social media, transactions records, cell phones, GPS, emails, research, medical records and much more…., the data comes from everywhere which has created a big talent gap and the industry, across the globe, is experiencing shortage of experts who can answer and resolve the challenges associated with the data. Professionals are needed in the field of Data Science who are capable of handling and presenting the insights of the data to facilitate decision making. This is the time to get into this field with the knowledge and in-depth skills of data analysis and presentation.
Have Fun and Good Luck!
