The Question is Usually Wrong
"Is this the right job?" assumes that right-ness is a property of the job. It's not. It's a property of fit between you and the job.
A job that's perfect for someone else might be terrible for you. A job that looked terrible might be exactly what you need right now.
What Fit Actually Means
Do you understand what you're being asked to do? Can you do it? Will you have the space to do it well? Does the way the work is structured match the way you work best?
Does the mission matter to you enough to care? Are the people people you'd want to spend 40 hours a week with? Is there room to grow into something more?
The Real Work
Before you can answer whether a job is right, you have to know yourself. What energizes you? What drains you? When do you do your best work? What kinds of people bring out your best? What environment do you need?
If you don't know the answer to those questions, no job will feel right. Because you're not actually evaluating fit. You're just taking what's available.
The "right job" is the one where you know yourself well enough to recognize it.
