The position was proposed by a recruiting company called Rinf. Before the on site interview, I had a call with a HR person. A researcher and the future manager took care of the technical interview. There were a lot of questions, but they were checking only basic computer science knoledge.

Took phone interview and selected for next round. Gave interview with 10 different persons and time of interview was 30 minutes for each. Overall it was a good experience to me.
