I passed the JS129 interview last Tuesday, September 1, 2020. This time, the interview was a bit harder to pass compering to the written assessment for the course.

I started learning JS 120 on July 13 and passed the interview assessment on September 1, 2020. That is 7 weeks of learning for around 20 hrs / week.
