They just called asking me to work with them without any interviews. It is a little odd that they offered an offer without even an online meeting. there are unpaid 6 weeks of trining

Very shady interview process that consisted of two rounds. I participated in the first round only. The interview was very sketchy. Firstly, the interviewer did not turn on his camera. When I asked them basic questions about their business, the interviewer was not upfront about it. The interviewer also asked whether I had any experience in data analytics. If the interviewer had read my resume, then the interviewer would have known that I had some experience. And, most concerning of all was that they asked me outright about my Visa situation. They moved me onto the next round, but I was sufficiently sketched by the last round that I declined to participate.
