Obsession with twngan

I just arrived back from Mountain View (again). My plane landed right after midnight. This company is in a very special position. It has a long history (7 years is forever in this industry), yet it has the mentality of a startup. It has a large team of engineers, yet the position I interviewed is more of a research position, requiring publishing a lot of papers and staying in the research community. It is also interesting to interview with someone who just reviewed one of your conference paper submission. More importantly, it is not extremely small in size (>100 employees), yet it makes decisions very fast: an offer comes within 15 hours of my landing...
