Looking for a little extra money this holiday season? A slew of major retailers are hiring and seasonal work could be a great foot in the door to full-time work down the road if you're currently unemployed or underemployed.

Who's hiring this holiday season?

While seasonal work isn't high paying, many retailers do look to promote from within when it comes filling full-time positions once the holidays wind down.

"We are always looking for great people who are passionate about serving customers," Nordstrom spokesman Dan Evans said in an email interview. "We do some hiring in advance of our Clearance Sale in November and hope many of the same employees will help us out during the holidays."

The jobs this year may go beyond the traditional floor showroom at retail. "Some of the best opportunities could be in the backroom, handling incoming and outgoing shipments," says CEO John A. Challenger of respected leading outplacement consulting firm Challenger, Gray & Christmas. "Job seekers should also look for positions at warehouses and shipping facilities associated with retailers and/or transportation companies."

Here's a look at who's hiring and how many positions they're looking to fill.

Avoid these common mistakes on job interviews

CareerBuilder.com interviewed employers to find out some of the most common interview mistakes made by job applicants. Read up and be sure you don't blow your chance when you get that call.

  • Don't answer your cell phone during the interview. My contention is that if an interviewer takes a call during an interview, well, that's totally rude. But they're the employer and you can't really do anything about it. But you doing it as an applicant? You have just told the employer that phone call is more important than the job opportunity.

  • Dress appropriately. Don't be either underdressed or overdressed. Know the culture of the company where you're interviewing and take that as a cue. Go on the company's website to learn about the corporate culture before interviewing to get a feel.

  • Don't be arrogant. While you want to do your research before an interview, you don't want to be a know it all. Be humble.

  • Don't talk trash about a past or current employer. I remember when applicants I've interviewed over the years would come in and tell me about what an awful place they work at now or have worked at in the past. Don't do that, even if your boss or work environment deserves it. You just come across as having a lousy attitude.

  • Don't chew gum. Employers say applicants will actually do this just under 60% of the time.

  • Know the right questions to ask. Not asking the right questions shows that you're not prepared for the interview. Again, use the Internet to research companies. Read press releases and whatever you find in the investor relations section of a company's website.  

  • Be genuine. This one comes from my own personal experience, not from CareerBuilder.com. Having personally interviewed many, many people over the years, I can tell you I don't want to see an actor. I want you to be who you are.
