I was interviewed by two ikaSystems employers. They were really friendly. I was asked about my daily work at previous full time work. It was a really interactive interview. Both the interviewers were really friendly.

All the questions are about your resume. What kind of technics are you using? How to solve some problems? How do you handle the big data? Things like that. All around your resume. So you would better prepare for your resume. And some behavior questions. That's all.
