Met with various executives over 2 rounds of interviews (about 6 people overall) in the head office. Interviews went well, and I was informed I was the lead candidate. I was surprised when I did not receive an offer, until a friend confided in me a few years later that an executive I had worked with at a prior company vetoed my hiring out of self-preservation (he was nearly terminated from our previous employer for an HR issue, and did not want that getting out). I was extremely disappointed, but fortunately had another offer. (That exec is no longer with the company.)
