So the biggest challenge I faced was when I started on my current position, I didn't have enough resources and I didn't get enough training. So I had to train myself pretty much and I keep practicing. I looked at like I used to get a little bit of training from my store manager but as he was busy he wasn't able to show me things again and again. So whatever times he showed me one thing I had to carefully look at it, practice and all that stuff and I always tried to learn about the system and went through the company training process which are some videos that the company provides but that's not enough. But yeah I had to go from there and keep learning and I was able to overcome that.
