how to explain roles and responsibilities in interview code example

Example: describe your role

I am responsible for maintaining our "test automation
framework" based on the POM and adding new test cases
to our automated regression suite.
I performed various types of testing, like; functional
testing, smoke testing, regression testing and back-end
testing.
I am also responsible, in my current project, to execute
Regression test when developers add new functionality to
the application or every end of the sprint.
I run the entire regression suit before each release, in 3
months. I analyze the test result. I provide a pass-fail
report. I monitor the execution to see if anything is
wrong, once it fails. If it fails because of my code I have
to fix my code. (Perhaps during that time, the application was
down, and I ran my script at the wrong time.)
But If there is really a defect, 
I log the defect and test it again until it is fixed.
As a Cross functional team member, I help the manual
testers, teach them basic automation framework, Java
and Selenium to make them part of the team, All to
improve productivity of the team. 
At least they can execute test cases and analyze
the results. I also try to help the
functional testing team whenever it's needed,
to execute manual test cases. And if there is
any defect that I am able to reproduce,
I log the defect to JIRA. In sprint grooming
meeting I always give feedback to the user
stories to make sure it is something testable 
and measurable.
For example: there were a user story said
after such and such change in the application
the performance should improve. I
I have asked the PO  what do you mean by
performance improvement? How do you measure the
improvement? After that he have come up with 
more descriptive user stories
Beside that I can tell you one of my responsibilities which I really
enjoy is user story generating sessions, because it is very
interesting from a user's perspective. Because we are the ones
testing the application all the time. I am thinking from the enduser 
perspective. I think I am doing good, by putting myself in
the end user's perspective. Therefore, when we attempt user story
sessions, we are making our acceptance criteria much better. So,
Business Analyst go over the user stories, they go over the
acceptance criteria, we ask questions we give feedback, improve
user stories therefore making our team more productive. Because
we have better, clear acceptance criteria. That makes us, our
requirements better, our code better, clearer and we are avoiding
some of defects in terms of the user story generation session
itself, instead of having unclear a user story, making unclear
code, making something wrong.
Also, as a part of the Agile Scrum Team, I participate in the
several walkthroughs meeting for the requirement reviews and
provide valuable feedback to the BA.
That is pretty much about %8o of my role as an automation
engineer in my current project.
