Avhan Technologies Java Developer interview questions

A company's hr called me for an interview. On the first day there was a two rounds aptitude and technical. It takes five hours of mine. Then they said you are on hold process because there are other candidates also in line. After five days I got the message that you have been selected for final round . I went there for final round and tech lead person asked me a same repetative questions like explain about your project and stuff. After completing he said me that hr person will let me know. After that same they didn't call me back. They just wasting candidate's time because they are already on a higher position and they doesn't care about anyone. Not this company, but nowadays every company does the same thing. I don't know why they even hire freshers.
