Pros
BlingABC is from my research one of the best paying companies currently out there. They have a very clear pay structure system which is fair for everyone. I started teaching my first class about 3 weeks ago, it is a large class but they give you lots of training and clear guidelines to follow when completing them so I feel very comfortable. The staff are very professional, the teachers are passionate about their job and there is just an overall positive atmosphere!
Kontras
As many people have previously mentioned, it does take a little bit of time for the schedule to build. The training process is long but in the end, I did find it to be useful. They are very particular about tech requirements and I have seen some teachers classes stop being scheduled due to not having enough CPU (even though the platform works fine).
