As I said in the title I got the job but I know I am not competent for this job because I do not have enough knowledge about this job. I feel like I stole the job from someone who is eligible for the job.

But I really need money, because I have six family members and I am the only one who earns money. My salary is the only income of my house.

Please tell me what I can do in this situation. I feel I really stole the job from someone else.

I am really confused and upsets me so please tell me what I can do.

Impostor syndrome (also known as impostor phenomenon, impostorism,
fraud syndrome or the impostor experience) is a psychological pattern
in which an individual doubts their accomplishments and has a
persistent internalized fear of being exposed as a "fraud".[1] Despite
external evidence of their competence, those experiencing this
phenomenon remain convinced that they are frauds, and do not deserve
all they have achieved. Individuals with impostorism incorrectly
attribute their success to luck, or as a result of deceiving others
into thinking they are more intelligent than they perceive themselves
to be.[2] While early research focused on the prevalence among
high-achieving women, impostor syndrome has been recognized to affect
both men and women equally.[1][3] Impostor phenomenon is not a mental
disorder, yet there is research describing various management styles
for this internal experience.

If they gave you the job they think you're good enough. Time to believe them over your lying brain.

Do your best to study and learn the skills and duties required for the job. You will improve your performance and gain confidence in what you do. Don't be afraid to ask questions and learn something new.

I'm going to say that if you've received the offer, you're likely qualified enough for the job. Impostor syndrome is a powerful thing. It's totally natural.

However, when you say this:

The thing which confuses me is that I defrauded someone who is eligible for the job where I stand and.....

It makes me feel as if you've blatantly lied on your skill set in order to get the job. Maybe you can provide more context?

If you've lied on your resume and are truly not qualified for the job, it's probably best to identify the areas in which you are lacking. Are these things that you can learn on the job quickly and with no serious repercussions? If so, get to work. If not, then it's best to probably come clean and apply for other jobs before this gets ugly.

You say you have a family of six and you are the only one to earn money. Who are your loyalties with: Are you loyal to your family and put food on the table, or are you loyal to some stranger who would laugh about you if you gave up your job to them?

You didn't steal someone's job. Nobody has the right to a particular job. You went to a job interview, you did well, you convinced the company to hire you, you do your work, and you get paid. It's between you and the company, not between you and some random stranger.

Here's what you do: Next morning before you go to work, you stand in front of mirror and say: "I deserve this job. I can do this job. I work hard, and I deserve what I get paid, and I deserve to be the one doing the job and getting paid. If there are things I don't know, I'll learn them and deserve my job even more." You say this loud. Act that way every day. And eventually, you will believe it. Your colleagues may believe it before you do. Your boss believes it now.
