Concentrix Software Developer interview questions

First on call and next was face to face in zoom meeting where in cal they speak about basic aptitude next was exam online then comes the face to face

Had two rounds of interview and also got the positive feedback for the same but after that there was no further discussion happen. Initially they said you will have. A final round of discussion.m with HR but I never got the call from HR team. I tried to follow up over a mail but they were not replying. If company does not want to hire please do not conduct the interview for timpass and waist the time of the employee
