Make sure its a job you want that your changing to,Reason i say this in the future if you keep changing jobs that won't look good on a resume.If i see a resume and they worked 2 months this job 4 months this job and maybe 6 months another job that screams they won't work somewhere long pass over them.when you go on the job interviews try to dress like the workers do there,And be early if your late your already screwed.And like said let them know i have a job you will put in a 2 week notice and your first day at work can be and say the date.This will look better on you for the next job,If i interviewed someone that had a job and told me they can start anytime ill pull the ill call you on them.Reason being if you will quit on them with out a notice you'll do it to me.
