What's the difference between SDE and WDE? I've seen this from the other side where there's a candidate we really like, but we found another that's a better fit for some reason. It may be someone they've worked with before or has a specific experience they want to take advantage of. If you read anything into this, it's that they like you so much they want to find a place for you. The easiest action for them is to hit the reject button and move on.
