Hr sent and interview and interviewed me, asking what I did and what do I know about airwallex. Afterwards she said she will review and let me know. Did not even get to meet the hiring manager.

There are 4 rounds and I stopped at 2 rounds. 1st round is sql question and basic ML question. 2rd round is pandas coding, case study and some ML questions. 2nd round case study is very ambiguous and they assume you're very familiar with their business process already(actually I'm not). The interviewer is not so patient and if you ask more info or definition of what he's asking he will not give to you. Overall not good experience.
