Had my first ever final interview as a developer after passing the first ever coding assignment, now can't stop thinking if I should have answered the questions differently.

I was very honest to my answer when they asked "How do you test your application?" As I started building the app with 0 knowledge about software development and know nothing about software testing. So I just told them the truth that I did not do any proper test, I just used a checklist and manual test to test my app and the app that I created for the assignment was the first app that I write a proper test cases and implement an automated test. The same goes to other questions like automated deployment and OOP experience. I just told them the honest truth even though I know that they are not the best practice. Did I just f*cked up the interview??

Arghh can't stop thinking
