The Data Science field has exceeded all estimates of career opportunities made in the last five years and outperformed with more than 2 times of the projected numbers. The Data Science career unarguably stood as the most desired job.

Also it is the fact that there are millions of Data Science jobs left unfilled every year due to the lack of qualified Data Science professionals. In the year 2021, there were close to 3.2 million of Data Science jobs left unfilled worldwide, of which around 2.0 million jobs are from Asia Pacific region.

On the other hand, many aspirants who pursued a Data Science course, gained strong foundation knowledge, did many learning projects, are finding it difficult to get a job in the Data Science field.

So the question: Why are many Data Science aspirants with good preparation finding it difficult to get their first job in the field of Data Science?

And the answer: Structured interview preparation. In this article we shall discuss “How to prepare for Data Science Job Interviews” in a structured manner.

1. Technical Readiness

A strong knowledge of Data Science concepts and practical experience in applying these concepts is one of the most important aspects of getting a Data Science job ready. Data Science is a vast subject and mastering all the Data Science concepts is difficult.

Technical readiness indicates that the candidate should be able to demonstrate key concepts which are relevant to the practical application of Data Science concepts to real-world applications.

The topics of the Data Science that is considered as essentials are as below

1. Programming - Python for Data Science

2. Statistics and Mathematics

3. Data Preparation

4. Feature Engineering

5. Machine Learning

6. Data Science Model Deployment

7. Projects & Internship

A strong foundation in key concepts of above topics and applied knowledge in solving data problems and machine learning modelling suffice the essential technical readiness for Data Science and Machine Learning Job interviews.

Resume Preparation

The resume is the first touch point with your potential employer. As per the research, most of the interviewers/initial resume scanners make-up their minds in less than a minute on glancing through the resume. So it is very important to present your resume not only in an impactful manner but also in a clean, simple and professional manner.

Here are the few areas to strengthen your resume:

First is First - Get through ATS

In most cases, Applicant Tracking System (ATS) has a built-in system to filter relevant resumes. These ATS filter systems work with simple keyword matching and density mechanisms. This means that ATS gives a high score for the resume which mentions the same keywords as in the job description(KD) key skills requirement section.

First is first, the resume has to get past the ATS, so it is important to fine tune the resume inline with the job description for every job application.

Prioritise Relevant and Important

It is a common practice to write the experience in the resume in chronological order. But reviewers would be more interested in the skills and experience that are relevant to the job description, so that they can evaluate the resume for the job.

It is recommended that the relevant skills and experience for the job be placed at the time and highlighted. The rest of the information can be presented below in chronological order.

Remove Not Relevant Information

It is equally important to either remove or minimise the not relevant information. It would be a distraction to mention your achievements, experiences and skills that are not relevant to the current job you are applying for..

Highlight Technical Skills

Always use a separate section- “Technical Skill”, to highlight the technical skills that are relevant to the job as mentioned in the job description.

Mention Participation in Relevant Events

It is a good practice to mentioned the participation in relevant events such as webinars, tech meets, conferences, etc., Only mention the events that are relevant to the job

Interview Skills

The data science interviews are usually on relevant skills and practical experiences, it is also important to have good Interview skills including sitting posture, eye contact, concise answers, professional mannerism, display positive attitude, being a good listener etc. There are a plethora of articles available to improve your interview skills but the key is to practise.
