Yes, that is the one they'll be most interested in since it's the one you're just leaving.
YES
Tell them your background.
Answer it by telling them how long you need before you can start the job. If you can start immediately, tell them that. If you need to give notice somewhere else, let them know and tell them what the notice period with your current employer is. The main thing is to be honest, don't make a promise you can't keep and don't just walk out on another job if you need to give notice as it won't do you any favours when it comes to references.
There are a number of things you could say to describe your current position in a job interview. You could say you are not employed for example.
You tell the truth.
tell me about your self?
A person will need to answer this based on what their current job responsibilities are. Someone else will not be able to know exactly what their job responsibilities are.
I never heard of anyone charging to interview people for job positions.
Get another job for more money with another employer and tell the current company why you are leaving in your exit interview. If you can not get another job with more money, then the current employer is certainly not under rewarding you are they?
Preparing for an interview for a graphic designer job is just like preparing for any job interview. You need to research the business you are interviewing with, and determine how they need you, then sell yourself.
When asked 'what other jobs are you applying for' in a job interview you should answer with the truth. Just tell the employer.
Standard questions during a job interview are "tell me about your professional experience". Depending on whether you are a novice or an experienced professional, you should share your previous job experiences. If you are a novice, then, you could tell anything that you think would be relevant for the job. You may provide a scope of your educational capabilities and strengths or any of your hobbies, etc.
