In recent weeks, recruiters for Consolidated Container Co. have seen job candidates arrive up to an hour early for interviews. Other candidates have alluded to financial hardships while in the hot seat, and one person even distributed bound copies of documents describing projects he completed for past employers.

These sorts of tactics aren't exactly winners.

In today's ultracompetitive job market, even getting an interview is a feat. Yet recruiters and hiring managers say many unemployed candidates blow the opportunity by appearing desperate or bitter about their situations -- often without realizing it.

'People are becoming a lot more aggressive,' says Julie Loubaton, director of recruiting and talent management for Atlanta-based Consolidated Container. 'They often wind up hurting themselves.'

At an interview, you want to stand out for the right reasons. To do so, you'll need to leave your baggage and anxiety at the door. For starters, wait until 10 minutes before your scheduled interview time to announce yourself. Arriving any sooner 'shows that you're not respectful of the time the hiring manager put aside for you,' says Ms. Loubaton, adding that a candidate who arrived an hour early made workers uncomfortable. 'Companies really don't want someone camped out in their lobby.'

Signal confidence by offering a firm handshake, adds Wendy Alfus Rothman, president of Wenroth Consulting Inc., an executive coaching firm in New York. Focus your attention on the interviewer. Avoid looking around the room, tapping your fingers, or other nervous movements.

No matter how you're feeling, keep your personal woes out of the interview process, asserts Ms. Alfus Rothman. Instead, always exude an upbeat attitude. For example, if you were laid off, instead of lamenting the situation, you might say the experience prompted you to reassess your skills, and that's what led you here. 'You want to demonstrate resilience in the face of unpredictable obstacles,' she says.

Meanwhile, show you've done your homework on the company by explaining how your background and track record relates to its current needs, adds Deborah Markus, founder of Columbus Advisors LLC, an executive-search firm in New York. This is particularly important if the firm is in a different industry than the one you worked in before. To stand out, you'll need to look up more than just basics on company leadership and core businesses. You'll also need to find out -- and understand -- how recent changes in the marketplace have affected the firm, its competitors and industry overall. Read recent company press releases, annual reports, media coverage and industry blogs, and consult with trusted members of your network. 'Companies that may have been performing well just a few months ago might be in survival mode now,' says Ms. Markus. 'You want to understand how [they're] positioned today.'

Also, be sure to show you're a strong fit for the particular position you're seeking, adds Kathy Marsico, senior vice president of human resources at PDI Inc., a Saddle River, N.J., provider of sales and marketing services for pharmaceutical companies. Offer examples of past accomplishments -- not just responsibilities you've held -- and describe how they're relevant to the opportunity. 'You must differentiate yourself like never before,' she says. 'You need to customize yourself and make yourself memorable.' liuxuepaper.com
