Much of your success on a new assignment depends on the impression you make in the first few minutes. Follow these "first-day-on-the-job" tips to elevate your chances of finishing a rewarding assignment.

Dress for success. Dress conservatively - make sure you know the corporate dress code, and err on the side of being conservative. Your appearance should always be neat - make sure clothing is clean and pressed and not too revealing.

Use good scents. Be mindful of your cologne or perfume; too much can overpower the senses, and can even cause an unintended allergic reaction to a co-worker.

Get a good night's sleep before every work day, but especially on the first day of a new assignment. You'll look refreshed and you'll be sharp and alert.

Be pleasant, but not overly chatty.  It's great to get to know your new coworkers, but save visiting time for lunch or a break. Everyone will get some work done and you won't be perceived as "pesky".

Listen carefully when a project or assignment is being explained to you. Don't be afraid to ask questions and take notes, and don't be afraid to admit if you don't understand something.

Arrive early for your new assignment and make sure you understand the directions to the location. If you're not familiar with the area, it doesn't hurt to find the location a day or two before you start.

Stay busy. When you finish a task, ask what else you can do. Never sit idly; it gives the impression that you lack motivation.

Never leave without saying goodbye. You likely will need to have your timesheet signed, anyway, but always announce your departure. It's good manners and promotes the impression that you are not sneaking away.
