I applied online and received a call from the HR. After a short conversation we booked an online interview, which took place a few days later. The interviewer did not know much about the specifics of this position, so the interview was quite generic. However, the interviewer was really nice and reassured me that even if this vacancy did not work out, they would soon have a similar project, so there was a prospect of me working for them one way or another. Unfortunately I never heard back from this company, not even after I sent a follow-up email, a few days after I was told I would receive a response. So I regret having invested time in this process. Totally unprofessional behaviour.
