What is being an software developer in test (SDET) like?
There are a lot of positions that are pure SDET positions. I'd be interested to hear from individuals who are or have had experience with SDET or have been at companies that have dedicated SDETs.

 1. What is the job like (day to day responsibilities)
 2. What kind of code are you writing (i'm assuming mostly unit tests, test runners, test automation)? 
 3. Is the career fulfilling for the long term, or is it mostly used as a foot-in-the-door into the company for a SDE position?
