This was my second time through with the Post, and (despite the offer) was my second bad experience. I interviewed for a lead role and received very positive feedback on what was (supposed to be) the process as described -- a screen, a combination behavioral/technical interview, and another leadership-oriented interview. However, the Post then decided to tack on another step in the process, around system/AWS design. As someone who has helped shape the interview process at his current company, I could tell that the engineer running this last step was very unprepared, and that this was something they were trying for the first time.
I have done system interviews before, and have always done well; unfortunately, the engineer conducting this portion was very insistent that it was supposed to be "quick and easy," and, when I asked questions about constraints and parameters -- you know, systems-building 101 -- they were clearly annoyed and unable to answer the question well. They also confessed to me that they hadn't actually conceived of a solution to their own interview question.
Later, I received an offer, but not one for the role I applied for, and the compensation number was, to be frank, insulting. It would have represented a large decrease from where I currently stand, and the Post was unwilling to negotiate with me.
