Recruiter contacted me via email and said that there would be an initial screen by recruiter and hiring manager to see fit. I was prepared for that. But suddenly the phone screen turned out to be full blown technical interview. If they informed me earlier then I would have prepared like wise. I felt like I was set up to fail.

Overall I did not have a good experience. At first, the interviewer called 5 minutes after the scheduled time, which for an interview is lack of professionalism. Nevertheless, I got the call and it was difficult to answer the questions since the interviewer would interrupt me, ask a different question and then after a couple more questions come back to the first one. The interviewer was a little bit dull as well, making it also difficult to get comfortable with when talking. Since the call did not go as smooth as I would have liked, I did not get the position. I do not have hard feelings, but I would recommend probably preparing a detailed in-depth explanation of your resume making it as short and concise as possible and be prepared to talk with a guy who is going to question all of your work even though you know is right.
