Learnt Java
automated testing
Accepted Job Offer
+1
I was a software intern working on a highly skilled web services team writing Java microservices back when they called it SOA :p

Anyway I was tasked to automate the generation of test messages from the test data provided by data vendor monthly.  We used these for E2E validation. 

I was making progress(slowly) when one of the mentors who was driving our pairing session reminded me to add a  colon ';' for the 5th time.

"Have you ever written Java?"
"Nope."

That night I got myself a book "head first into Java" and was able to finish the project by the end of the next week, automating the generation of thousands of test cases and saving dozens of hours of manual effort.

The quick turn around and ability to learn what mattered earned a full time job offer!
