Interview all went OK, but then the process stopped without any explanation. The first interview the recruiter did not really know much about the job. The second interview went a bit better with another two technical people present in the phone conference. Each interview lasted an hour or so.

one round with management and two technical interviewers. Approximately one hour interview with hiring manager, one hour interview with two technical peers or team lead in the second interview. HR offering the salary package is not very professional though.
