Questions posées lors d’un entretien d’embauche pour Java Senior Programmer chez NetApp

Hr called me and asked me if am interested to apply for the particular opening and after that one more hr called me and scheduled interview, 2 people joined interview and I've all the questions they asked, after 1 week another hr called me to schedule next round, have attended next round and almost answered each and every question.Then after 2 weeks hr called me and informed me that "the feedback is positive as you're currently serving notice, I'll ask my team to reach out to you" it has been almost 2 weeks no one reached out to me, my only concern here is if you're not willing to hire people then why did you conduct interviews and waste our time and please stop playing with the feelings of the job seekers, if you got positive feedback from the interview panel why the hell you're taking such a long time to process ? I suggest job seekers to think before attending NetApp interview as they don't value your time and talent
