How do I talk about those bad job experiences when asked about them in a job interview?

 

I spent six years in my first job out of university working at a financial services company before moving on to not one, but two other companies in the same sector which had extremely toxic atmospheres. I spent less than six months at both and now I’m going to interviews again, but I can tell the interviewers are not impressed with these two jumps. I know I’m supposed to put a positive spin on the experiences to turn them to my advantage, but I feel I’m just not coming up with the right words. What can I do to show interviewers that I’m not someone who can’t take a bit of hardship? Or should I massage the facts a bit?
