I've been looking for work for the past 4 months and the experience has been a very mixed bag. At first I didn't have any current certifications (I had a CCNA at one time, but let it lapse) and I thought my experience would get me in the door (I've been in the business for about 12 years). Employers wouldn't even call me for an interview.
Then last month I bit the bullet and took and passed the Network+ exam.
To be honest, a large number of the questions on the exam were dated and the chances of running into the scenarios in the real world are slim (thick-net, thin-net, token-ring, etc.).
But since I got the cert, I've had three calls for interviews and one call-back.
The cert only gets you to the interview. It's up to you to sell yourself and show your skill knowledge during the interview. If you only know enough to pass the test, then it'll show during a good IT interview.
