Three interviews in total (First via telephone with HR, second personnal with hiring manger and third with technical engineer via zoom meeting to check technical level). Office and employees seemed nice and open. Offer received after completing 3 interviews successfully.

They ghosted me after 4 rounds of interviews. They always replied very fast (within 1 day) between the interviews, but when it was time to tell me the result, they never contacted me again. Not even a plain negative reply. As a job seeker, I found this is frustrating and disrespectful because I was waiting for their reply for a long time. I sent a follow-up email after 2 weeks. They replied to that one, and they explained that 1 of the 2 positions has been already filled and they asked for my patience to decide about the second one. But after that, again, they never contacted me again. Apart from this, the job details, the offered salary and the company vibe were positive, and I wanted to join them. Too bad that they don't have a policy for properly reject the applications, meanwhile they emphasize during all the interviews the importance of good customer service.
