First interview was about some general information that I wrote on my resume. By the end of the same call I was asked to select a time for a phone interview. This phone interview was about behavioral questions and a small case about analyzing data. A situation was described as I wrote a script for a client and it run for 5 mins and I got the result, however, this client gave me another set of data, this time, my script runs forever, and the question is: what might went wrong? Then 10 days later, I got an email saying I was invited for a second round phone interview. It's basically projects and experiences I've done and some SQL questions, together with 2 riddels. Then the next day I was informed that I was welcomed for an onsite interview. I'm still waiting to schedule that interview.
