Explaining a layoff without sounding bitter - what worked for you?

They always ask why I left, and I freeze. I am in Tucson, in case local advice matters. I do not want to blame the company. Do you mention numbers?

If a company has been in the news for layoffs, you can mention that. Often the interviewer already knows.

Say it plainly and move on to what you can do. Interviewers usually move on if you do.
