First is phone call for 3 - 5 behavior questions. Then 2 rounds of tech screenings, each takes 2 hours with all multiple choices questions. Questions covers Java, python, SQL, and knowledges of computer system.

The final round is the worst interview I have ever had. The interviewer asked me to write a simple algorithm, I did it exactly correct as it is the perfect solution from Leetcode but he cannot even understand and said my solution makes no sense. I explained to him why this is correct but he did not care at all. This interviewer showed no respect and did not even care to answer my question. He keep telling me "I have another meeting soon", then turn off meeting page without any common courtesy. What funny is that he dressed like enjoying vacation at a beach while their HR reminded me to have a formal dress when I got the invitation. Such a waste of time.
