We haven't had a better job market in years. The US Department of Labor stated that at the start of the month there were over 5 million job openings available. In the last 7 days, Indeed.com (my favorite job search website) said they had posted 670,432 new jobs.
The interviewer asks: Why has it taken you so long to find a job?
It’s difficult to believe that employers are still asking this type of question. Don’t they read the newspapers or listen to the news? If they were informed, they would know the answer; i.e. jobs are very scarce and difficult to find these days, and unemployment is still high, despite improvements in the economic picture.
