I have finished my graduation in 2016, and after that, I had prepared for the competitive exams. Now, I want to move my career into the IT sector; I don't have any prior IT knowledge. Can you please suggest me which course is right in the market?

Hey Yadla, 

For better understanding, I needed some answers from you?

1. As you mentioned, you have finished graduation. Which subjects you had in your graduation? 
2. Do you have any friends who are working in private corporates? If yes then in which domain? 
3. What government exam were you preparing? It will help me know your aptitude experience because I don't want your preparation to go waste. 

Let me know the answer. I will try to help you.

Hey Yadala, it depends on how you want to proceed and how much money you have. If I had to suggest to you:

1. Find a job. (but how?) Learn a language, preferably, Java. Learn DSA in it as there are many free youtube lectures for it. Then apply for an unreputed company, i.e. startups. At first, improve and grow, there no one can stop you.
2. While doing the job, do some web development and apply for more prominent companies.
3. In the end, you will land at big MNC in 2-3 years earning 1 lakh per month.

IT is a Vast area. First, you have to decide what is the domain you are interested in. Some examples are Graphics Designing, Web Designing, Digital Marketing, Programming, Mobile application development etc. Once you have decided your domain then search for the latest tools used in the field you have selected. For example, if you have chosen Graphic Designing, you need to learn Adobe products like Photoshop, Illustrator, and Indesign.

As per my understanding, you should go for software testing. Nothing is launch in this world without testing.
Testing is 2 type of manual and automation.
Manual testing has no programming concept, while automation has little programming concept.
Hence, first, go for manual testing for the quick job, then go for automation.
This is a faster and secure job.
