How to prepare for networking interview questions: Insider advice

Even after getting a foot in the door with a stellar resume, job candidates need to be prepared not only to show technical prowess but to demonstrate that they're a good fit for the company.

During a job search, flunking tough networking interview questions can land a resume in the "rejection" pile faster...

than you can say "dropped packet."

Fortunately, found some interview veterans willing to share their secrets on how to get the job.

George Bock, vice president of IT at Sole Technology Inc., estimates that he conducts some 50 interviews a year for a variety of positions. To get a foot in his door, he suggested one simple principle: Know what you're after.

"The resume is going to be the first entry point into any interview, so making sure you've got your job description and know what you're looking for before you start the process is critical," Bock said. "I hope that people take the time to modify their resume for my job description."

And while it may be tempting to tout all your certification accolades over the past decade, Bock said he really does not want to hear that you are an SQL server guru when you're applying to be an Exchange administrator.

Instead, job seekers should focus only on the most relevant certification, leaving less relevant credentials (if the subject comes up) for the interview and keeping the resume focused on why you are not only the perfect candidate for a job but the perfect candidate for this job.

Besides, for Bock and other potential employers, the value of the certifications is dropping, particularly compared with demonstrable experience and proven skills in a given area.

According to a recent report by Foote Partners LLC., the average certification has decreased in value 7.3% over the past two years, while the average skill set has increased in value 10.5% over the same period.

But when emphasizing these skills on paper, be prepared to back up your claims in the interview.

"I think everybody embellishes on a resume. The good candidates embellish for the right reasons and back it up," Bock said. "The people who write they can do everything, I don't believe."

And if an applicant starts to include statistics or throw in brand names, Bock guarantees that he will dig into those areas.

"If they can't explain how they managed a Windows network or fixed a specific problem ... that tells me they're blowing smoke," he said.

The personal connection

The technical conversation in the interview is just one small factor for Bock. Technical qualifications are easy to glean from a resume. In an interview, the most important factor is how well he sees the applicant fitting in with the company.

"If he doesn't fit into the overall strategy or plan I have for the department, then that's going to be a deterrent for me, and that only comes out in the interview," Bock said. "I probably spend half my time in interviews figuring out what makes a person tick."

That leads to one of Bock's favorite questions: When have you not succeeded but still learned?

"People who can articulate experiences like that do well," he said. Sole Technology has a corporate culture of risk-taking and is OK with failure, he said, as long as the employees learn and take that experience with them.

Bock also suggested that a good fit for company culture may be reflected in interview apparel, even if that goes against conventional dress-to-impress wisdom.

"We're very laid back, very comfortable -- sneakers and comfortable shirts," he said. "Try to accentuate the fact you'll fit in."

This is a good article. Tells that employers need people who can solve the problems rather have answers to questions. I especially like this statement: ".. the value of the certifications is dropping, particularly compared with demonstrable experience and proven skills in a given area. "
I like the view that  "I hope that people take the time to modify their resume for my job description."     My analogy is that you may be selling a fancy limo but client really needs or wants a bicycle.
Be prepared of the "Left Field" question. Sometimes you will get asked a question that may seem a little bizarre.  This it to test how quick you are on your feet and you problem solving skills. They may ask you how you came up with the solution and to possibly justify your reasoning. Don't glamorize your resume if you cannot back it up with the skills needed.
