Applied online. First contacted by an HR and asked about my background. Then I was scheduled to take an coding test within 3 hours. It is one of the classical coding test--- spreadsheet calculator. Two days later I was told I passed the coding test and they would like to move forward to the first technical interview. The first interview was about my background, research, then a coding question and a probability question. I gave several solution to the coding question. I nailed it and was able to move to the second technical interview. It was about projects on the resume. Then a couple of coding questions. Again I did really well. The interviewer told me the next step should be onsite. But one week later, I contacted the HR for the update. She told me my background doesn't fit for the position. They passes me. Really sucks!
