CIOs, CTOs and hiring managers should apply these four elements when assessing tech candidates.

Hiring in today’s IT world is as complicated as ever. With changing technologies and decentralized architecture, along with cloud-focused, software-defined life cycles, how should chief information officers and chief technology officers look for good resources?
First let’s focus on key technologies and architectures that are here to stay. Today’s microservices-based architecture is a classic decentralized architecture and usually a smaller piece of the puzzle in a larger technology eco-system. Secondly, you cannot escape from cloud technologies where you are using infrastructure as a service (IaaS), platform as a service (PaaS) or software as a service (SaaS). Lastly, structure of data is more important than ever. Businesses are seeing the value of combining internally generated data with external data to create various metrics that drives decisions. Data comes in the form of unstructured (Excel and Word files), semi-structured (XML and JSON) and of course structured (SQL Server and Oracle).
So, what should you be looking for when hiring? What kind of questions should you ask? Many organizations give a practicum or case study to the candidates to test a real-world scenario. What kind of practicum (or case study) would you want to give potential candidates to assess their knowledge? How would you want to structure the interview and the case study? In my opinion, CIOs, CTOs and hiring managers should focus on the following four elements when hiring their resource pool:
1. Ability to solve puzzles: Most organizations are adopting microservices-based architectures when migrating existing applications or developing new ones. This new paradigm is analogous to solving a puzzle as overall solutions are broken down into smaller puzzle pieces in the form of microservices. The puzzle pieces can be as granular as you want. For example, a single microservice can be broken down into types of data it consumes or even the environment (or even container) it runs on. The key point here is to ensure the candidates have problem solving capabilities by keeping the big picture in mind along with the small, granular one. Hiring managers should design real life case studies and give them to the candidates as a hiring criterion.
2. Ability to deal with various forms of data: Ensuring data translates into meaningful information is what matters at the end of the day, as ultimately information is what is used to make decisions by the businesses. To make things further interesting, businesses prefer flexibility and options in the way information is generated and used. While data forms the heart and soul of all businesses, hiring managers often lose sight of how important it is for candidates to have a robust understanding (and/or background) of the importance of data. Data comes in many forms as mentioned. Hiring managers should ensure that candidates can deal with conversion, integration, security and manipulation of data from one form to another. Again, this ability can be tested by giving candidates a real-life case study.
3. Ability to collaborate: Testing for interpersonal skills is one of the hardest things for hiring managers. The best way to test for this ability is to design the case study in a way that allows the candidate to use independent problem-solving skills and the ability to explain/sell the solution of the case study to the team the candidate will be working with. This is one the most effective ways to test interpersonal, collaborative and critical thinking. You will be able to test the following: How the candidates explain themselves; do they use pictures and diagrams to make their solution compelling; and how efficient are their solutions.
4. Ability and willing to work with the old and the new: This is probably one of the most underrated area when it comes to evaluating a candidate. We all want to work on greenfield solutions where you start from scratch. However, that is hardly the case. In fact, most organizations have a set of old solutions and technologies already in place. It is very important to make sure candidates are willing and able to work on and work with other people’s solutions, ideas and even existing legacy systems. This area is also one of the hardest areas in which to test. Some ways the hiring managers can address this gap is by being transparent and honest about the role and have a dialogue on the topic.
Every organization has human resources that deal with the verification processes as it relates to prior education, background and employment. Further, IT organizations may be looking for specific technical skills. The four elements I have outlined above are in addition to standard and basic checks, and specific technical skills needed. I believe that if CIOs and CTOs focus on these four elements, they will be able to retain quality resources for years to come. Lastly, these elements can be applied to multiple roles, such as architects, developers, testers, business analysts and project managers.
