Dexian Senior Fullstack Developer interview questions

The first interview was with this HR person, which asked me basic questions about python and react. Then I had to go through an assessment on Glider AI, twice because the first attempt was full of questions about web scrapping which wasn't the main subject of the position (API Fullstack developer). Then I had to go throug other too interviews, one with the client (Exxon Mobil) and the other with the HR management of my home country (brazil) to undestand the whole hiring process. In the end, I accepted their offer and sent my personal information (ID, address, etc), they said a laptop would be sent to my address and someone would contact me to go through the onboarding process but no one ever did. After that, they stopped responding my contact attempts (email, whatsapp and LinkedIn). I even tried to reach out to other developers I found on LinkedIn that worked to Dexian, but they didn't replied. My advice: Be careful with this company and don't share your information before making sure that there's a real job opening.
