- Data Analytics Consultant: If you want to broaden your horizons, you could be providing consultancy for data analytics solutions. This way, you could be your own boss, serving multiple clients at the same time and providing insights to their business problems.
- Data Analytics Manager: This position is also in demand. If you love technology and leadership at the same time, then you should look forward to becoming a Data Analytics Manager. Your technical proficiency along with social skills go a long way in making you successful in this domain.
2. Applying for jobs: Now that you have a fair idea about which Data Analytics job roles might suit you, it’s time to search for jobs on the right platforms and apply.

Similarly, Indeed and Glassdoor list more than 1000 jobs for Data Analytics Consultants. Go through the job postings carefully, and apply for the ones that you think would suit your skills the most.
3. Leverage your experience; present case studies: Prior work experience is always an icing on the cake when you attend a job interview. So, brush up on the business processes that you implemented, how you analysed data and what approach you followed to get to the solution. More often than not, interviewers look for your knowledge and capability in business analytics, apart from your expertise in data analytics tools. So be ready with business case studies and real-time problems. You can pick up case studies from your past projects or refer to case studies from sites like analyticsvidhya.com, deloitte.com and careerprofiles.info. Explain the business problem, the data processing steps followed, algorithms used, how you arrived at the solution and how you resolved the challenges. This will showcase your competence in data processing and analysis and prove your worth to your potential employers.
4. Be prepared with thorough technical knowledge required for the job: Basic knowledge of analytical tools like R or SAS (or as specified in the data analytics job description) is necessary if you’re attending a data analytics interview. Brush up your knowledge on concepts related to data import and manipulation, such as reading non-standard data, performing heavy-duty processing (SQL or macros), efficiently combining multiple datasets, and the same.
Apart from concept-related questions, you may also be asked questions around R, SAS or Python programming, correlation, probability and regression, as well as on distributed computing frameworks like Spark, Hadoop, etc. The questions can revolve around the following –
– Python models
– Syntax style used when writing SAS codes
– Commissioning nodes into the Hadoop cluster
– Global and local variables in Python
– The difference between Hadoop and RDBMS
– Performing regression testing, etc.
5. Study the Basics of Statistical Concepts: There are chances that you’ll be asked questions on analytical algorithms, which is in turn related to statistical concepts. So, you might as well review statistical concepts like model validation measures, hypothesis testing outcomes, rejection criteria, statistical assumptions for algorithm implementation, etc. before the interview.
6. Impress the interviewers with your knowledge about the organisation: Before you appear for the interview, make sure that you study about the organisation’s primary business and the work that they do in the domain you’re applying for. This bit of homework will go a long way in impressing your employers. This also gives you the advantage of showcasing your skill sets against the real-world issues that the organisation is trying to solve, and you will be able to convince your potential employers about how you are prepared to contribute to the growth of the business.
