Do you think that a data scientist has a place in the design and development world?
Considering the amount of data generated with every single activity on the web, it is imperative to make sense of this data and get a better picture.
We are surrounded by data.
Organizations of every scale, type, and industry use and need data to refine their product ideas, design, and development.
A data scientist possesses the ability to read the data, or we can say that they have the ability to read between the lines and understand the number’s language.
Before hiring a data scientist, it is more important to understand the roles and responsibilities of the person with reference to your organization.
This is important. Because when it comes to understanding data, there are a lot of noises coming from the cohorts. The right person has the appropriate frequency to listen to the dynamics and develop readable conclusions.
It is possible that not everybody on your team is as enthusiastic to hire a data scientist like you.
So, the first thing is bringing everybody on board with this decision.
Because a data scientist can influence the organizational decision down to its core.
If not, this, especially the operational processes pertaining to the product or service development, can be moved by the insights of a data scientist.
Before hiring, check the areas where you need the assistance of a data scientist.
So, you need to create a draft of the current operational issues you might be facing. The problems might differ from organization to organization.
But as an example, a logistics company troubled with higher delivery costs can use a data scientist’s help to frame better operational practices, leading to cost reduction.
Recommendations by a data scientist can be given in any form. Every organization needs to deliver their service and product while ensuring complete customer satisfaction.
Now, to achieve that satisfaction level, you need the insights about a customer and how they react to your product and service offerings. A data scientist can provide such recommendations that allow molding your services and products according to consumer behavior.
Lastly, we have data management and arrangement that is provided by business intelligence. BI is about staying connected to the organizational operations in all its entirety. This includes getting a sense of the KPIs, growth prospects, sales, revenue, customer acquisition, costs, expenses, etc. Understanding these statistics and the way they shape your organization can help you frame better processes.
Everything begins with problem specifications. Based on this, we can identify the type of data required to understand the problem. Then we have the methodology followed by proof of concept and validation.
Once the solution is validated, it is implemented. Further maintenance, improvisation, and iteration are also a part of this entire process.
So, when you hire a data scientist, it is essential to measure the candidate’s skills and understanding of these aspects.
Irrespective of your industry, a data scientist should be adept in understanding and working with these concepts and technologies –
The thing is that if you were hiring a data engineer or a data researcher, things would have been easier. It is because in both these cases, the skillset and the mechanism to judge the same is straightforward.
But a data scientist’s work profile lies between business intelligence, mathematics or statistics, and programming.
That is why, apart from the skills listed above, a candidate with experience and knowledge in econometrics, time series analysis, natural language processing, and image recognition can be preferred over others.
In the three domains that we mentioned above, which are essential to hiring a data scientist, there are some specific skills that you should look for while taking interviews.
Starting with Mathematics or Statistics, ensure that you include questions about calculus, algebra, descriptive and inferential statistics, probability, and other similar concepts.
This will allow you to rank the candidates on the basis of their expertise to handle complex mathematical calculations.
Secondly, you need to look at the core aspects of machine learning or programming. This includes understanding the candidate’s ability to work with;
The motive of getting an idea about these concepts is to know whether the candidate can build data pipelines.
Be it in a digital or non-digital format, you need the data collated and scrapped off with the best bits available for the reader. A well-built data-pipeline is vital to enhance data security, understanding, and applicability.
Lastly, under business intelligence, you need a scientist who understands your business and processes. More importantly, the right person should identify the problem accurately and then make apt solutions for the same.
These solutions will be based on the metrics and insights gathered from the residential data.
Yes, very much.
The reason being that you cannot expect a college graduate to work on all three dimensions of a data scientist.
It takes time to become a jack of all trades.
While setting the interview tests and questions, for the verbal or personal interaction rounds, include the following aspects –
Now let’s come to the test. Taking a real-time test of the candidate is really important. The candidate must possess the right combination of skills and talent required by your organization. This includes the right mix of academic intelligence and practical knowledge.
Onboarding a candidate who is not adept in all the fields of data science is riskier and leads to wastage of time and resources.
There are softwares to assess the real-world skill evaluation of the candidates. Without the help of these platforms, it can take a long time to create a test on paper. So, it is better to use premade software-based tests for assessments.
While creating or selecting the tests, try to include problems containing the aspects of the three dimensions listed above.
If not this, make sure to include a mix of questions based on machine learning, business intelligence, and statistical problems. This way, you will get a better picture of the candidate’s ability to solve your organization’s real-world problems.
Your assessment tests should be self-explanatory, time-bound, contain general desensitized data, direct, and gradated (gradual increase in the difficulty level).
