In the first step, I had a screening interview with a HR specialist who gave an excellent presentation of the company and the position, including tasks and challenges. It was a very pleasant and professional conversation with very fast feedback. The next stage was a video call with a key figure - one of the founders. But this, I beleive, is due to the specifics of the position. Anyway, it was a very pleasant, open and welcoming conversation.
In general, in my case, I can describe the process as professional, fast and very friendly towards the candidate. I can draw a conclusion about a good and healthy atmosphere in the company.
