There are too many irregularities, no proper communication and lack of transparency. Also there are only contract based jobs so think twice before leaving your full- time positions. And I am not sure how they schedule interviews and even with 3 mode of communication (email, watsapp and their web-app) they schedule interview for very next day at time of their own preference.

It seems they have added a practical interview section. Here they asked about real world questions. This is great but if you don't pass your previous tests, you can't advance to this one.
