Passed initial interview, tech pre-screening, then took the 4-hour interview loop. Recruiter mentioned that they would reply by the end of the week, 3 weeks ago. And then nothing, no response to follow-ups and no updates on Action Center (stuck on scheduled interview), and the job listing is still available. I had to take 2 days off my current job and study through the weekend for the interviews, it seems a bit unfair that they did not even take the time to send an automated rejection email. Anything I can do?
