10 Hardest IT Jobs to Fill


1. IT Trainer

IT trainer plays a role in IT world and he requires having a certain skill set. By itself, the position can be hard to fill. However, becoming a trainer will differ in different ways starting from a Typical IT job together with the need of traveling. This is why not everyone is capable to work in the industry.

2. Project Manager

The problem when it comes to hiring of the project manager, it is the self-imposed and the requirements of the PMP certification. Some companies focus more on the PMP certification while the certification itself is expensive and it is not easy to get. It is not easy to get the certification at the beginning while the certification itself is not clear-cut. If you want to get the certification, you will need to be managing some projects already, but it will also be hard for you to get the job in the first place. This is why this talent pool is too small and other qualified candidates may be kept out.

3. Director, CTO and CIO of IT

The IT leadership role is not easy to fill out. A candidate should be able to show the skills that are not easily gotten from the IT training. Some companies may choose to hire the leaders who have nonexistent and weak technical knowledge or they may hire a technical person and wish that such person can learn the business skills needed to become a success. It is hard finding a person who has both skills and the position can be left to the unqualified person.

4. Help desk Staff

The problem when it comes to this job, the person who has all the qualifications you need, he will not be willing to be given the salary you are offering. Most people are capable to work in this position regardless of the challenges and the technical skills needed. The help desk staff will have to answer the calls, to know the right time to close the tickets and to deal with some angry people over the phone. However, the companies pay less for this role while trying to squeeze the salaries. However, when companies pay less, they also make it hard for qualified people to apply.

5. Specialized Programmer

The programmer has to be able to work on the mobile application, operating system with the device drivers. He should understand what they have in common and do the best job with this. However, there is also a problem with developers since some jobs are too specialized and only a handful of the developers can do this. Others such as the mobile application programmers have a high demand and some companies may stay with the unfilled positions for many months.

6. Pre-Sale Engineer

The pre-sale engineers are IT-related job that requires different talents in addition to the technical ones. In order to make a hard position in filling, the job will require someone to travel too much. It is always important for the seller to use demonstration before making the sale. The job is more customers oriented and the person should present it in person, which is not easy for the IT people who are accustomed to doing everything on their own. The Pre-sale engineer should have a heart of the salesperson at the same time an IT pro mind. This is something tricky.

7. Technical Writer

This is not about the bloggers and what they do. It is more about writing the manuals of the product and the help files. There are reasons why such tasks will fall on the developer’s shoulder, even if the company wants to pay a technical writer. The writer should be able to write in coherent manner while using the language that a buyer will be able to understand. This is why hiring a technical writer may be hard to get and some good ones are even harder to get.

8. Product Evangelist

A product evangelist is a person who is the face of a company. This comes at the technical side of a business. They are the one that gives the presentation the technical conference in the entire world and they have forums where they answer the question, blog and they reach the people at the social media. They should have the technical knowledge and some of the IT jobs will involve traveling. A person to work in this way, he should have the passion towards his job and his company. He should also have all the soft skills with a technical knowledge needed in handling the job. This is why, you can find a person who is great as an evangelist at a certain company, but he can do a poor job when he is hired for another company.

9. IT Author

Writing the technical blog with articles is considered to be easy job and some people may do it like a part-time job. However, only a few people are able to put the roof on their heads using this work. Even if it is easy to find people who are willing to try out this job, it is hard to find a person who is willing to work on the job for a long period and to stick with the company and to be part of your team. Another person is that some people may have great ideas when they get hired but in few months, all these ideas have been used up and they do not know what else to do. Only few IT authors are able to produce high-quality product over many years.

10. Legacy and Maintenance Programmer

This is a job that few people are willing to take and it can be disguised as something else. This is a job that requires the maintenance of existing application and some that had been around for many years. Some few programmers will want to take up this job since it is the end of their career. This is because something which looks cutting edge now, it will be obsolete after some few years. Someone who works for this job, he will have to reinvent himself outside of the workforce.

What Does Technical Support Mean?

Technical support (tech support) refers to a range services companies provide to their customers for products such as software, mobile phones, printers, and other electronic, mechanical or electromechanical products. Technical support services usually provide users with help in solving some common problems rather than providing training on how to use the product.

Techopedia Explains Technical Support

Technical support is usually delivered over telephone, via email, over chat (IM) or using special software or software extensions that the user can employ to directly contact tech support. Technical support representatives are very familiar with the ins and outs of the products for which they provide support. If there is a problem that cannot be solved by the tech support, it is escalated to the development team and logged as a bug that should be fixed by a future product update or the next product iteration.

There are a few key types of technical support:

  • Time and Material: This type of support is common in the tech industry. Also known as “break-fix” IT support, the payment of the materials and technician service charge falls upon the customer for a pre-negotiated rate.
  • Managed Services: This is usually given to large-scale customers rather than individual consumers. A list of well-defined services and performance indicators are provided to the customer on an ongoing basis for a fixed rate, which is agreed upon on contract. Services provided could be 24/7 monitoring of servers, 24/7 help desk and the like. This may include on-site visits when problems cannot be solved remotely.
  • Block Hours: This is a prepaid support system where the customer pays for a certain amount of time, which can be used per month or per year. This allows customers to use the hours flexibly without the hassle of paper work or multiple bills.

IT Infrastructure Examples

Your company’s infrastructure is all of the elements that go into your network. There are essentially 3 pieces to IT infrastructures: infrastructure hardware, software and networking. There is some overlap for these infrastructure components, but his table shows a quick snapshot of typical examples for each. Keep reading to get an in depth look at what makes up your IT infrastructure hardware.


  • Servers
  • Data Centers
  • Personal Computers
  • Devices
  • Routers
  • Switches


  • Software Apps
  • Operating Systems
  • Virtual Machines

Infrastructure Hardware

Hardware is just one IT infrastructure example and consists of any IT component you can touch. Therefore, while your software and networking are part of your infrastructure, they are not part of your infrastructure hardware because they are not physical components. Hardware includes but is not limited to the items listed below:

  • Servers
  • Mobile devices
  • Hard drive
  • Network cables
  • Printer
  • Storage devices
  • Laptops

What Infrastructure Hardware Does

Hardware IT infrastructure does a number of things, including allowing you to connect to your network and have access to the outside world. It also stores your data, and allows you to recover and use your data. Any infrastructure that involves more than one computer or person should also provide a means by which to communicate with the people or devices involved in the network.

The responsibility for the maintenance of the IT infrastructure falls to the owner. For example, you might own your own server, but you might not own the router that allows your network to access the outside world and others in the network. That may belong to your ISP and be their responsibility.

Technical (Bundle COURSES)

What does a data scientist do?

Data scientists determine the questions their team should be asking and figure out how to answer those questions using data. They often develop predictive models for theorizing and forecasting.

A data scientist might do the following tasks on a day-to-day basis:

  • Find patterns and trends in datasets to uncover insights
  • Create algorithms and data models to forecast outcomes
  • Use machine learning techniques to improve the quality of data or product offerings
  • Communicate recommendations to other teams and senior staff
  • Deploy data tools such as Python, R, SAS, or SQL in data analysis
  • Stay on top of innovations in the data science field

Data analyst vs data scientist: What’s the difference?

The work of data analysts and data scientists can seem similar—both find trends or patterns in data to reveal new ways for organizations to make better decisions about operations. But data scientists tend to have more responsibility and are generally considered more senior than data analysts.

Data scientists are often expected to form their own questions about the data, while data analysts might support teams that already have set goals in mind. A data scientist might also spend more time developing models, using machine learning, or incorporating advanced programming to find and analyze data.

What’s the Demand?

By 2026, the number of data scientist employment is expected to grow by 27.9 percent, as reported by the BLS. The Bureau estimates that by 2026, the market would be worth USD 322.9 billion. As more and more businesses depend on data to make crucial decisions, the need for data scientists is expected to keep rising.

What are the Eligibility Requirements?

Courses leading to a Data Science certification are open to participants of any experience level, from complete beginners to seasoned experts. The completion of an undergraduate degree is the one and only requirement needed to sign up for a full- or part-time course. A previous background in coding is not required. The minimum admission requirement would be an honours degree or post-graduate diploma in Information and Knowledge Management, IT management, Information Systems, Marketing or a cognate discipline at NQF level 8 with an overall average of 65% or above.

Roles and Responsibilities

Data Scientists are responsible for collecting both structured and unstructured data, locating appropriate data analytics tools, promoting data-driven decision-making, and completing data-related tasks such as cleaning, wrangling, analyzing, and segmenting. In certain cases, they may also be tasked with designing and executing machine learning models, sharing findings with relevant parties, and keeping abreast of the latest developments in the field.

What is Computer Networking?


What Is Cisco Networking?

Computer networking refers to connected computing devices (such as laptops, desktops, servers, smartphones, and tablets) and an ever-expanding array of IoT devices (such as cameras, door locks, doorbells, refrigerators, audio/visual systems, thermostats, and various sensors) that communicate with one another.

How does a computer network work

Specialized devices such as switches, routers, and access points form the foundation of computer networks.

Switches connect and help to internally secure computers, printers, servers, and other devices to networks in homes or organizations. Access points are switches that connect devices to networks without the use of cables.

Routers connect networks to other networks and act as dispatchers. They analyze data to be sent across a network, choose the best routes for it, and send it on its way. Routers connect your home and business to the world and help protect information from outside security threats.

While switches and routers differ in several ways, one key difference is how they identify end devices. A Layer 2 switch uniquely identifies a device by its “burned-in” MAC address. A Layer 3 router uniquely identifies a device’s network connection with a network-assigned IP address.

Today, most switches include some level of routing functionality.

MAC and IP addresses uniquely define devices and network connections, respectively, in a network. A MAC address is a number assigned to a network interface card (NIC) by a device’s manufacturer. An IP address is a number assigned to a network connection.

How is computer networking evolving?

Modern-day networks deliver more than connectivity. Organizations are embarking on transforming themselves digitally. Their networks are critical to this transformation and to their success. The types of network architectures that are evolving to meet these needs are as follows:

  • Software-defined  (SDN): In response to new requirements in the “digital” age, network architecture is becoming more programmable, automated, and open. In software-defined networks, routing of traffic is controlled centrally through software-based mechanisms. This helps the network to react quickly to changing conditions.
  • Intent-based: Building on SDN principles, intent-based networking (IBN) not only introduces agility but also sets up a network to achieve desired objectives by automating operations extensively, analyzing its performance, pinpointing problematic areas, providing all-around security, and integrating with business processes.
  • Virtualized: The underlying physical network infrastructure can be partitioned logically, to create multiple “overlay” networks. Each of these logical networks can be tuned to meet specific security, quality-of-service (QoS), and other requirements.
  • Controller-based: Network controllers are crucial to scaling and securing networks. Controllers automate networking functions by translating business intent to device configurations, and they monitor devices continuously to help ensure performance and security. Controllers simplify operations and help organizations respond to changing business requirements.
  • Multidomain integrations: Larger enterprises may construct separate networks, also called networking domains, for their offices, WANs, and data centers. These networks communicate with one another through their controllers. Such cross-network, or multidomain, integrations generally involve exchanging relevant operating parameters to help ensure that desired business outcomes that span network domains are achieved.

Only Cisco offers a complete portfolio of modern network architectures for access, WANs, data centers, and cloud.


Types of computer networks

While similar in their overall objectives, various types of networks fulfill different purposes. Networks today are classified in the broad categories below.

A LAN is a collection of connected devices in one physical location, such as a home or an office. A LAN can be small or large, ranging from a home network with one user to a large enterprise network with thousands of users and devices. A LAN may include both wired and wireless devices.

Regardless of size, a LAN’s particular characteristic is that it connects devices that are in a single, limited area.

A WAN extends over a large geographical area and connects individual users or multiple LANs. The Internet can be considered a WAN. Large organizations use WANs to connect their various sites, remote employees, suppliers, and data centers so they can run applications and access necessary data.

Physical connectivity in WANs can be achieved by leased lines, cellular connections, satellite links, and other means.

A network built for a large organization, typically called an enterprise, needs to fulfill exacting requirements. Since networking is crucial for any modern enterprise to function, enterprise networks must be highly available, scalable, and robust. These networks have tools that enable network engineers and operators to design, deploy, debug, and remediate them.

An enterprise may use both LANs and WANs across its campus, branches, and data centers.

Service providers operate WANs to provide connectivity to individual users or organizations. They may offer simple connectivity, in the form of leased lines, or more-advanced, managed services to enterprises. Service providers also supply Internet and cellular connectivity to their customers.
