I got asked a lot of hard questions in recent round of interviews about the one gap out of a history that's quite long. Haunts you if you don't have a good story up front.
The same applies to short periods of employment. Take your time during updating the CV to create convincing language-neutral explanation, because „they were among the stingiest cheapskates in this part of the continent”, or „their codebase was monumental dried pile of Java” will not work in your favor.
