The interview process consisted of two system design questions and one normal coding question, along with a few technical questions here and there. All questions were answered quite well, but the outcome was negative. I was informed that we couldn't proceed further, as the panel felt I was good in the majority of areas. "It is what it is," was the outcome.

I don't understand whether they actually want to hire or just show job openings to be present in the market. Perhaps they intend to hire someone else and just conduct all these interviews with other candidates, wasting their time.

This has happened multiple times where they said I performed well in the interview but couldn't offer me the job. Seriously, stop wasting candidates' time if you don't have a job to offer. I've seen the same job reposted again and again, and for a single vacancy, the same job has been open for months. How can this happen if there are multiple candidates in line for interviews?

Project in detail and technologies around that.
