I interviewed for a job at an ecommerce company a few years ago,  didn't get the job,  with most of the (stated)  reasons  being related to  my having no experience working with an ecommerce company (I worked for a payment systems company at the time). There is an interesting job with a different ecommerce company being advertised at the moment. The job spec really pushes for someone with ecommerce experience.  So what is it that ecommerce developers do that other developers don't do?  I've always picked up the field of the companies I work for really quickly and ecommerce doesn't seem anymore complex than any other I've worked in.... Thank you :) 
What do ecommerce developers do that other developers don't?
