I've gotten every job I've ever interviewed for and here's my advice: practice your interview skills, google most common interview questions and practice practice practice!, show up 5 minutes early, be nice and personable with the receptionist, be dressed as nicely and professionally as you can, take a professional notebook and pen, have copies of your resume, have a firm handshake, be confident, maintain eye contact, brush up on their company/background/work, ask intelligent questions, don't be afraid to highlight your achievements and past work experience (you're there to sell yourself!), be eager and show you're willing to learn, grow, and add value to their team, tell them you'd be honored to be part of their company, ask them what the next step in the process is. That night send a thank you email to everyone you spoke to and reiterate the things above, add a personal touch from something spoken about in the interview. Follow-up in a week.
