While I advocate honesty on a resume and even in an interview, I don’t necessarily believe that in every circumstance – at all times – the “interviewee” needs to (or should) share every piece of personal info. One way to handle the question of a gap between your jobs coming up during an interview is to:
a) be proactive and NOT put a gap (a flag) on a resume to begin with by putting the four digit years instead of months and years on a resume, or by putting the number of years instead of the four digit years. ! I can’t imagine a interviewer taking the time or interest to then ask you the exact months of when you worked there – so that might help to avoid the whole issue of the gap from the get-go.
b) Another way is to say, “I’ve been exploring my options and interviewing to find just the right company for me where I can continue to grow as an individual while utilizing my diverse skills to contribute to its success.”
