Freelance IT Engineer: Is there too much to remember in the IT industry? Is it tough to have no experience? Explanation of experience


I write articles about what IT engineers need to study in the industry. It is said that there is a lot to remember in the IT industry. You may think this, especially if you are new to the industry, but the truth is, there aren’t that many. This is because many people get discouraged at first because they receive too much information, but most engineers decide on their own areas of expertise.

IT industry has too much to remember

If you are a beginner, you may think that there is too much to remember in the IT industry. The reasons why this is the case are as follows. When you are a beginner, you try to know everything and do your best, but if you take the wrong direction, you will be frustrated. Please use this as a reference if you are thinking of changing to a technical career. It would be a good idea to take the time to think it over and understand it before deciding how to behave.

I haven’t decided which field I want to pursue

If you have no experience in the IT industry, you may not know much about the industry. In the IT industry, there are many other areas of expertise besides sales. There are many types of jobs, as listed below. There are the following types of jobs, and some people may not be able to grasp what they are like. In fact, in an industry where many types of jobs are created every day, the key is to think about what is good and suitable for you.

  • System Engineer
  • programmer
  • database engineer
  • data scientist
  • data engineer
  • server engineer
  • network engineer
  • hardware engineer
  • tester
  • Project manager

I’ve listed a few, but there are many more. Each job requires specialized terminology and knowledge, so beginners tend to try to memorize all of them. However, in reality, it is common for employees to perform only one specific job. Annual income, overtime, service content, and even learning content vary depending on the environment and job type, and development requires an understanding of new systems.

I haven’t decided which industry I want

In the IT industry, there are cases where the ordering party is the pharmaceutical industry, and there are cases where the order is from the financial industry. Especially when formulating specifications and creating basic design documents, there are technical terms depending on the industry, and knowledge is also required. In the IT industry, there are a lot of contract cases. We receive orders from various industries.

  • consulting industry
  • financial industry
  • insurance industry
  • pharmaceutical industry
  • retail industry
  • restaurant industry
  • Distribution industry
  • construction industry

This is just a quick list, but if you’re a beginner, you’re trying to memorize all the industry knowledge and terminology. However, in reality, career plans are often limited to one industry. No one knows everything.

What beginner engineers in the IT industry should do

As mentioned above, in the IT industry, there are many different industries and jobs that you come into contact with, so if you try to remember everything, you will get stuck. This is because there is so much information that the human brain cannot absorb. Here’s what beginners should do from now on: Qualifications and the level of difficulty and difficulty of the work will vary depending on the industry, occupation (management, development, testing, networking, etc.), and even the workplace. The basic knowledge required of employees and the way they respond are also different.

Decide what job you want

First of all, you should decide whether you want to be a programmer or a data scientist. In general, those who become specialists are more valued. On the other hand, generalists will be able to do their work evenly, but they tend to be half-hearted.

It is desirable to study the skills and knowledge necessary for each job. If you are a programmer, you will study which language to use, what frameworks are available, and what kind of OS is available. If you narrow down your field, you will naturally be limited in what you can study.

determine the industry

Especially when you are a subcontractor, you will receive orders from various industries, so there are many cases where the industry changes all at once. If you are in charge of requirements definition or basic design, the required business knowledge and experience will change. If you try to remember everything, you will fail. So what I recommend is to narrow down the industry to some extent. In the case of finance, it is preferable to focus on work at a bank or securities company.

It is extremely difficult to know all the industry knowledge. As you can see from the fact that every industry has different requirements for human resources when hiring, the knowledge required for each field is completely different. The human brain has a limited amount of memory, so let’s limit it to one.

gain experience

Get a hands-on experience of what it’s like to work in the field. It will be difficult at the stage where your IT skills are low, but even if you are worried about a project, those around you will support you, and as you understand and grasp the work, you will be able to figure out countermeasures and feel a sense of growth. So let’s keep learning. We recommend that you seek employment at a company that interests you. Engineers who are always active often have clear career change goals. Let’s take advantage of the good parts of ourselves.

hone your abilities

If you are a beginner, it is a good idea to gain experience and hone your skills at the same time. In the beginning, you may find it difficult and stressful because your skills are low, but of course, as you continue to work, you will improve your professional skills. Learn knowledge from books, etc. and be evaluated by your seniors. If you can truly learn and improve your skills, your seniors and superiors will evaluate you. Of course, self-study is also useful and allows you to grow. Due to the shortage of human resources, wages are likely to increase.

There is also a freelance path if you become a specialist

If you figure out what job you’re good at and what industry you’re good at, you’ll become accustomed to being a specialist in that field. This will increase your market value and increase demand. Once you become a specialist, you will also be able to work as a freelancer. It is not impossible to earn 500,000 yen or 1 million yen per month if you can do the job. First, decide what you want to do and what you want to achieve. Feel free to choose what you like and learn from a wide range of sources. By taking action, you can enrich your private life and increase your value in society.
