How to get a job in the field of Data Science¶

More than 90% of the people who start learning Data Science have this one common goal in their mind; how to get a job in this field. There is no magic to get a job in data science, but some simple steps to follow religiously which enhance the chance of getting the job significantly.

In order to master these simple steps, we need to understand what data science is all about.

What is Data Science all about?¶

A data scientist is expected to analyze the data given by their clients and find out some meaningful insights out of it, so that it can help the client make more profit.

For example, a company is selling a bar of soap for Rs 10 and 100 people are buying from him annually with a revenue of Rs 1000.

In case he increases the price to Rs 11 and still all his 100 customers are buying from him then it will surely increase their revenue significantly.

However, if the majority of their customers switch to a substitute brand, then that would ba a huge setback for company resulting in huge loss.

Data Science can study the past data and predict whether customers would still buy the product or they would switch on increasing the price. Hence, the company can formulate their business strategy accordingly.

Data science or data analytics can answer tons of such business questions and help the companies in their business strategy making.

So now the question comes what should a candidate exactly study to master data science?

What should you learn to master Data Science?¶

There are certain algorithms, called Machine Learning Algorithms, which is the main brain for data science. This algorithm analyzes the entire data and extracts all the hidden insights out of it, all by itself.

It will predict the future which will make it easy for the marketers to formulate a business strategy. E.g. If a bar of soap is being sold at Rs 10 and 100 people are buying and the Machine Learning algorithm predicts that if we increase the price by Rs 1 still almost all the people will buy from us.

The marketers will surely increase the price to earn extra profit. A full case study of such an algorithm can be found click here and click here

There are different types of such machine learning algorithm, which one needs to master, in order to answer all types of business questions. A business question could be like Whom should you ask for donations for a charity or Identify if a patient has cancer

All these Machine learning algorithms will be used with a software. At the moment there are 2 software which are mostly getting used in the entire world - Python and R Programming (henceforth will be referred to as R).

Hence, one needs to learn either Python or R or both, along with the Machine Learning algorithms. First you should learn the full coding (programming) using Python or R followed by business statistics and then machine learning.

Nowadays, there are certain advanced level algorithms named Deep Learning and Extreme Gradient Boosting methods, which are increasingly gaining popularity. These skills earlier were good to know but now they have become must know to crack an interview.

A typical python course should be like Python course part 1 and Python course part 2

Either of Python or R along with Machine learning is a must know for a candidate but there are certain other skills which are good to have. MS Excel and SQL are such skills, which will certainly add extra weightage in the resume.

After getting all the required skills how to get the coveted job in the field of data science?

How to get the job in Data Science?¶

The first step to get yourself hired as a Data Scientist is to have a professionally written resume. Your resume should be prepared in such a way that then recruiters search the job portals with key words, your resume should show high relevance.

It's quite imperative that there are a few million people who are also learning data science and have mentioned it in their resume too. Hence, your resume must be professionally built and should include all the key words of high relevance.

Once the resume has been built, you should start applying through the following channels:

1. Job portals like Naukri.com, Shine.com etc.
2. Linked in connect
3. Through friends and acquaintances who are already working

Among all the above-mentioned channels, Job portals are most efficient way of searching for jobs.

You need to keep on applying for different jobs till you start getting interview calls. Interview calls will not come from the next day after applying for the jobs.

It will take time to increase your CV's visibility; which might range from a few weeks to a few months' time. Normally people start getting calls after 2-3 weeks' time.

Once you start applying, the frequency of getting the calls increases. However, during all these periods of time the job applicant should keep on practicing dummy projects and appear for mock interviews.

This is the key factor to keep yourself motivated and well-versed with the subject, which will ultimately reduce the chances of failure in interviews and finally get your coveted job.
