It took over 3 months to be interviewed by 4 different people and to complete a writing test, a drug test, and an international background check. They were in no hurry to hire someone, which should have been a red flag. In fact, they did not need another writer at all, and I was idle most of the time. They may have been trying to replace people who left in order to get the head count back up. If they're not paying much attention to your portfolio, or the best practices of other companies you've worked with, it's another red flag that they're only paying lip service to hiring and developing talent.
