You created some of your own luck by making a good impression and asking them questions during the interview. It shows them you are interested and have initiative. The 'luck' you have no control over will just happen.

Sometimes the interview and selection process takes a long time at companies. I was involved in hiring in my previous job and just getting decisionmakers together to select a candidate took time with busy schedules. It might take the full 2 weeks.

I hope you get it!
