I have 1 interview policy

1. Take it.
   1. Doesn’t matter if you are not going to take the job or if the initial job offering was too small.
   2. Taking the interview will:
      1. Allow yourself to test your knowledge.
      2. Get yourself confidence for when an interview really matters to you.
      3. If you get an offer
         1. It will make you feel safe, just in case you suffer a work force reduction (WFR)
         2. You can always ask for more, now they know you are worth it =).
