I stayed at one job for just five months. When I resigned, I found out that two others resigned the same day. That did not look good for our boss. Later, she got fired. Then, her boss disappeared. Then, the president disappeared after only a few months. A guy at the agency I managed had once been thrown in jail by the FBI for misusing election funds. I just knew I needed to Get Out.
Thankfully, one interviewer saw the place on my resume and said, "Oh, I hear that place is a mess. I worked with someone who worked there. I don't expect you to say anything bad about the place in an interview." She kindly let me off the hook, and I learned that word about bad companies does get around.
Unfortunately, I then left that place to go to another mess of a place. I made two poor decisions in a row! Ugh. I lasted two years. I felt like I had to stay after the first fiasco-of-a-place.
But, you know what is important? More important than this one job where you have a toxic situation? You have to go in and DO THE JOB. Do not sit back and wait for them to ask you questions. Do your research and go in with a report or a PPT to show them exactly what you would do for them. This has won me many job offers and led me to the fantastic job I have today. =-)
