I got an email about proceeding to the next stage of the interview, after sending my CV. I have chosen a time slot on the online calendar to schedule a call and additionally written an email to the recruiter. After one week without a replay and a secend follow up email I was asked to choose time slots again. I have done it two weeks ahead, written a follow up email after two days and then again - and got no replay. Extremely unprofessional and with no respect for the candidate.
